[[caption-width-right:350:When it comes to annoying the Flash, the Fiddler doesn't [[{{Pun}} fiddle around]].]]

->''"I remember every little thing as if it happened only yesterday. I was barely seventeen... and I once killed a boy with a Fender guitar. I don't remember if it was a Telecaster or a [[AllGuitarsAreStratocasters Stratocaster]], but I do remember that it wasn't at all easy. It required the perfect combination of the right power chords and the precise angle from which to strike."''
-->-- '''[[Music/MeatLoaf Jim Steinman]]''', "Wasted Youth"

Musical assassins are [[ProfessionalKillers hitmen with style]]. Who needs guns when you can lay waste to your enemies with a carefully-calculated concerto? Techniques start out at {{Brown Note}}s and only get more ridiculous from there. These assassins are especially popular in old Chinese martial arts movies. Advantages of such a combat style includes invisible attacks that move at the speed of sound (Duh) which makes it difficult to be blocked by conventional methods like other weaponry. However this is normally traded off with a high required skill level, especially when it comes to aiming sound waves.

And why stop at {{Professional Killer}}s? Video games, for one, are rather fond of {{improbable|Weapon}} music-powered weaponry. Note that weapons (like guns) merely [[SenselessViolins disguised as instruments]] don't count; that's cheating. Neither do [[InstrumentOfMurder instruments that double as weapons]] or [[InstrumentalWeapon weapons used as instruments]].

SubTrope of ArtAttacker.

Compare MagicMusic, DiscoTech, ThePowerOfRock, MakeMeWannaShout. See also BrownNote, which can be used by a Musical Assassin to cause insanity or death; DreadfulMusician, for musicians who merely make you ''wish'' you were dead; and InstrumentOfMurder, which is used by musicians for physical attacks.

Not to be confused with ''Theatre/{{Assassins}}'', the musical.



[[folder:Anime & Manga]]
* In ''Manga/ArataKangatari'', there's Kikutsune, whose hayagami Kisaru manipulates sound. His whistling once brainwashed [[spoiler: Hiruha]], and he used soundwaves to obliterate not just an airship, but also [[spoiler: Yataka's zokusho]]. Then there are his zokusho, who used their hayagami's to steal the hearing of the people in their domain.
* Azawa Kodame in ''Anime/HandShakers'' is an IdolSinger fittingly her wepons becomes more powerful when she puts on a performance mid battle. Despite it leaving her wide open, this power up can be very devastating if her opponent isn't expecting it.
* Fou Lafine of ''Anime/BtX'', whose WeaponOfChoice is a violin. Unlike Kurumada's examples in Saint Seiya, disabling X's auditory sensors ''did'' block the attack. Unfortunately Fou was no slouch in combat either.
* ''Manga/{{Bleach}}'' has the Visored Rojuro "Rose" Otoribashi, who can kill you by playing his electric guitar.
* [[MeaningfulName Noise Marie]] From ''Manga/DGrayMan'' uses this, his innocence binds Akuma in a net of holy string that summons the hymns of angels, causing a BrownNote on its victims. We also had Daisya earlier in the series, whose Miracle Bell's chimes utterly ruined his foes [[ImprobableWeaponUser after he kicked it into them like a soccer ball]]. [[spoiler: [[DroppedABridgeOnHim Doesn't help him any against Tyki though.]]]]
** General Cross also uses one, or more specifically his second weapon, [[AnimateDead The Grave of Marie]], does. Marie was an exorcist whose voice could paralyze every Akuma who hears it regardless of how strong they are. Cross "repurposed" her after her death, making him even more powerful than he already is.
* ''Anime/DarkerThanBlack'' features an opera singer who can use resonance to destroy objects and stop hearts.
* ''Anime/DigimonAdventure'''s Etemon used music to control his Dark Network, which can influence anything electronic (including those pesky {{transformation trinket}}s, keeping all the {{Mon}}s stuck at [[SleepModeSize Child level]] (Rookie in the dub)).
** ''Anime/DigimonAdventure02'''s Arachnemon (spelled Arukenimon in the dub, but pronounced the same way) could control insect Digimon with her flute, sending swarms of them as {{Mooks}} and temporarily [[BrainwashedAndCrazy turning Stingmon and Digmon against the rest of the team]].
** Shoutmon of ''Anime/DigimonXrosWars'' is themed around rock music, so most of his attacks are named after types of rock, he uses a microphone as a staff weapon, and his Soul Crusher attack turns his singing into his microphone into a blast of fire.
* ''Manga/FairyTail'' has two. Vidaldas, a freakish rocker modeled after a KISS member, who takes control of people with music and makes them fight, and Lullaby, a sentient, soul eating flute that devours the souls of those who hear it's melody... and also turns into a [[AttackOfThe50FootWhatever giant wooden demon]].
* Neon in ''Manga/FlameOfRecca'' uses a Madogu in the form of a flute that manipulates sound waves.
* In ''Manga/FushigiYuugi'', [[spoiler:Amiboshi]] can use flute music to soothe, hypnotize, and even kill people.
* ''Manga/FushigiYuugiGenbuKaiden'' has celestial warrior Urumiya. Whenever he sings, he disables his enemies powers and drains their energy.
* In ''Manga/HunterXHunter'', [[SpellMyNameWithAnS Bonolenof]] plays music that either summons or creates weapons and fighters at his disposal. His body is punctured with holes and reeds making him a living woodwind instrument, so he's also a DanceBattler as this is how he plays himself.
* In ''Manga/KatekyoHitmanReborn'', one minor villain - M.M. - uses a clarinet that functions [[StuffBlowingUp as a microwave]], by using sound vibration to agitate water molecules and thus rapidly heating objects.
* ''Anime/GaoGaiGar'''s Mic Sounders the 13th (and his 12 preceding brothers) has music-based powers. He can use Disc M to cancel out an enemy mech's abilities, use Disc P to [[ThemeMusicPowerUp empower other GS-Ride-based mecha]], and use Disc X to destroy things. In fact, the reason Disc X isn't used to destroy every enemy mecha that shows up is that, unless it is precisely tuned to perfectly match whatever he's dealing with, he runs the risk of destroying ''everything'' with it, including the Earth.
** In the OVA, he also plays a [[http://www.youtube.com/watch?v=yr6oyFy4oxU bass solo]] [[spoiler:[[WeaponisedLandmark USING THE SUSPENSION CABLES OF THE TOWER BRIDGE]]]]. [[CrowningMomentOfAwesome And wins]].
* Nonon Jakuzure, one of the Elite Four members in ''Anime/KillLaKill''. Unusually, instead of using an instrument, she utilizes a {{tank|Goodness}}[=/=][[CoolAirship airship]] armed with enormous speakers that fire music-themed projectiles such as sonic booms, razor-sharp music notes, recorder missiles etc.
* The finale of the first ''Manga/LupinIII'' manga series has Lupin up against a conductor whose assassins and explosives are in sync with his music.
** A later ''Anime/LupinIIIRedJacket'' episode would have a conductor who could control the minds of people listening to his music by waving his baton.
%%* ''Anime/{{Macross7}}'': "LISTEN TO MY SONG!"
* Shirabe of ''Manga/MahouSenseiNegima'' who is also a DreadfulMusician.
* Shiho Munakata's Element in ''Anime/MaiHime'' is a flute that lets her control sound waves and give orders to her CHILD, Yatagarasu.
* The Black Beauty Sisters in ''Manga/MermaidMelodyPichiPichiPitch'' sing to stun the Mermaid Princesses. Likewise, Yuri plays a piano.
** The Winged Ones in [[OddlyNamedSequel2ElectricBoogaloo Pure]] sing as well with various effects. [[VillainousCrossdresser Lady Bat]] can put his victims to sleep, [[DragonLady Lanhua]] can split into twelve [[SuperDeformed mini-musicians]] and force her listeners to dance until they die, and Alala can shoot stars that strike her targets.
* In ''Anime/{{Mononoke}}'' one of the monsters uses a ''biwa'' (Japanese lute) to inflict dangerous hallucinations on the unlucky humans it comes across.
* Tayuya from ''Anime/{{Naruto}}'' has a flute that can make illusions and control summoned demons.
* ''Manga/OnePiece'':
** Scratchmen Apoo. What's his instrument? ''His own body'' - he has a Devil Fruit that turns his body parts into instruments. He is a living orchestra. What can he do with his music? How about cymbal crashes that dismember people, and drumbeats that cause explosions?
** A somewhat lesser example is [[DemBones Brook]] of the Straw Hats. Prior to the TimeSkip, his music only served as an accompaniment (no pun intended) to his fighting style, creating his epithet, "Humming Brook." The most he could do with it offensively was instantly put his foes to sleep. But two years later, when he's tapped into the full power of his Devil Fruit, this trope intersects with MasterOfIllusion.
* In ''Anime/{{Pokemon}},'' music is an [[JustForPun instrumental]] part of [[WanderingMinstrel Nando's]] battle style.
* Early on in ''[[Anime/ReadOrDie R.O.D. The TV]]'', the Paper Sisters face off against an enemy whose weapon of choice is... a huge pipe-organ. Which projects walls of sound that breaks down their Papermaster powers, and just generally knocks them around. (It can also conduct psychological warfare by using 'infrasound' to distract and stress out the intruders without them realizing.)
** Let's not forget about Beethoven's suicide orchestra in the ''Anime/ReadOrDie'' OVA.
* Kanaria from ''Manga/RozenMaiden'' attacks by playing her violin.
* ''Franchise/SailorMoon''
** Sailor Mercury plays a magical harp to perform her Mercury Aqua Rhapsody, which attacks the enemy with water.
** In the manga version Sailor Neptune plays a violin to perform the Submarine Violon Cord. Differently from the Mercury Harp, this is a completely ordinary violin (as much as a Stradivarius can be, at least.
*** ''Anime/SailorMoonCrystal'' gives her another unnamed attack that can stun multiple opponents with the sheer pain caused by the music.
** Ail from the Makaijuu filler arc of the first anime uses his flute to awaken the Cardians and give them instructions. However, this has its limits - when An isn't around to pick out a Cardian for him, Ail tries to summon one randomly and accidentally summons a Cardian that doesn't obey him.
** In the live-action ''Series/PrettyGuardianSailorMoon'', [[spoiler:Zoisite]] uses the piano to compose attack songs and then, by playing the completed piece, creates various effects, including summoning a youma, allowing an ally to teleport, and long-distance targeting of various people and objects (e.g., [[spoiler:princess-related]], including a visitor to Tokyo, a picture-book, and a girl who merely [[spoiler:identified too strongly with the princess in a storybook]]) with effects that range from unexplained sickness to SpontaneousCombustion. Good thing the BigBad is patient, because [[spoiler:Zoisite]] sure doesn't rush the process.
** In ''Manga/CodenameSailorV'' multiple [[EvilDiva youma disguised as idol singers]] use songs to hypnotize people and drain their energy. Mimete would later do the same in the main series of the manga.
* ''Manga/SaintSeiya'' has several characters:
** The Ghost Saint Lyra Orpheus from first non canon-movie and his two {{Exp|y}}ies: the Benetnasch Mime (lyres, though Mime's armor can turn into a harp) from anime-only "Asgard Arc" and the Silver Saint Lyra Orphée. All three use a lyre as weapon, share the same music and a similar attack where the [[RazorFloss lyre's strings trap and shred anything]]. Plus, Mime and Orphée have MagicMusic abilities. Mime can create illusion while Orphée can put to eternal sleep his opponents.
** The Spectre and Orphée's rival, Sphinx Pharaoh. He use an harp as weapon. His attack "Balance of Curse" technique rip opponent's heart and evaluate if is good or bad man.
** The Mariners Siren Sorrento who use a flute to weak and destroy opponent's mind. His music is so powerful that it leads directly to the brain; destroy your eardrums is useless.
* Kidaf Gillot from ''LightNovel/ScrappedPrincess'' used an instrument to command [[spoiler:robotic]] bugs for assassination.
* ''Anime/SenkiZesshouSymphogear'' has the leading cast, collectively called "Valkyries", as {{Magic Idol Singer}}s fighting partially with their voice. During battle, they sing their {{Leitmotif}} in order to weaken enemies and fight properly against them. Even the background music changes actively to fit the theme of the situation. The "Assassin" portion comes as part of their LimitBreak: a solo that creates a near-infinite amount of strength at the cost of their life.
* Lena from ''Anime/ShamanicPrincess'' plays a flute to control vine-like magic tendrils. She doesn't usually attack with them directly, though she can do so in certain circumstances.
* Soul of ''Manga/SoulEater'' uses his skills as a pianist and general musical knowledge in order to, well, [[JustForPun orchestrate]] the black blood and control his own insanity to increasingly devastating effect.
** Also, when he and Maka were fighting Arachne, [[spoiler:he was able to use her own spider webs to transmit Maka's anti-demonic wavelength into everyone to prevent them having their heads torn apart and also to injure Arachne herself.]]
* A villain in ''Anime/SpeedGrapher'' would count as one of these; when he used his powers, his body essentially ''turned into a speaker system''.
* ''Anime/SuitePrettyCure'' uses this a few times, first with Cure Muse (the masked version) conjuring a magical piano keyboard for some of her spells and later with Cure Beat's Love Guitar Rod, [[InstrumentOfMurder the magical guitar]] which turns into [[AnAxeToGrind a battle ax]] and shoots exploding rings of magical death.
* Midvalley the Horn Freak from ''Manga/{{Trigun}}'' uses the music from his saxophone to tear people apart. [[InstrumentOfMurder It also has a machine gun in it.]]
** A flashback in the manga reveals that he used to be part of an entire band of Musical Assassins. Their modus operandi was to take out the entire audience to hit their target.
* Florsheim once used a musical assassin monster with a [[BrownNote paralysing flute]] in ''Manga/TentaiSenshiSunred''. Sunred kicked him in the shins and made fun of him, ruining his concentration.
* Nearly every major character in ''Manga/ViolinistOfHameln'' has some sort of music-derived powers.
* Azami from ''Anime/WeissKreuz'' uses a violin as his weapon.
* The witch [[spoiler:form of Sayaka, who was already music-themed because of her music-related wish,]] Oktavia von Seckendorff from ''Anime/PuellaMagiMadokaMagica'' sucks out her prey's souls with her music.

[[folder:Comic Books]]
* ''ComicBook/TheFlash'' villains the Fiddler and the Pied Piper can wreak havoc with a violin and a flute, respectively. In the ''Countdown to Final Crisis'' series, Pied Piper even destroyed a Brother Eye/Apokolips hybrid with Queen's "The Show Must Go On." Probably one of the best examples of a Musical Assassin ever.
** The Fiddler had a female successor named Virtuosa whom has only ever appeared in books featuring the ComicBook/SecretSix, which is fitting since she was created by Creator/GailSimone. Virtuosa claims that she's an ardent admirer of the original Fiddler and took up his violin and legacy after his death in honor of him. She in fact had something of a fan girl moment when Fiddler was revived as a Black Lantern during ''ComicBook/BlackestNight'' and offered his violin back, though he was more interested in ripping her heart out.
* The antagonist seemingly destined to cause TheEndOfTheWorldAsWeKnowIt in ''The Apocalypse Suite'' arc of ''ComicBook/TheUmbrellaAcademy'' is the appropriately-named White Violin.
* The Piper in ''Adventures In The Rifle Brigade'' is a Scottish bagpipe player of over 100 years of age whose talent with the instrument (his current set was crafted from the flesh of the fellow who broke his last one) is unnatural to the point of tipping the scale all he way back into unbearable. Men have torn their own heads off to escape his music.
* One ''ComicBook/UsagiYojimbo'' story featured a series of killings with a flute-playing ghost as the primary suspect. [[spoiler:It wasn't him.]]
* Johnny Guitar and Dr. Sax in ''ComicBook/AvengersTheInitiative'' can level entire buildings with their guitar and saxophone, respectively... but they've been losers as supervillains, being passed over for every possible team-up because they were either too gimmicky, not mutants, or not gimmicky enough.
* Dr. Crescendo in ''ComicBook/TomorrowStories''' ''Greyshirt'' happens to be a MadScientist in addition to a violinist - and attempts to use his sinister music to prove his long-mocked theories true.

[[folder:Fairy Tales]]
* ''Literature/ThePiedPiperOfHamelin'': The 1440s German legend about a rat-catcher who, back in 1284, freed the city Hamelin (Hameln in German) from rats by luring them with magical pipes into the Weser River. When the townspeople wouldn't pay him for his services he used it to lure their children into a cave, from which they were never seen again.

[[folder:Fan Works]]
* Used in ''Fanfic/ManchesterLost'', as a cross between this and ThePowerOfRock. Beating up Satan with nothing but Don't Stop Believing by Journey, albeit performed by Archangels.
* In ''[[http://www.fanfiction.net/s/5055274/16/The-Graduation-Class The Graduation Class,]]'' a ''Literature/{{Discworld}}'' fanfic in which the author has several characters who fall into the AscendedExtra category, after their names are given in canon, one with a very slight elaboration. And they are all Assassins. This trope was used by [[MeaningfulName Emmanuelle les Deux Epées]] from [[FantasyCounterpartCulture Quirm]] who kills someone by playing a certain set of cords on a violin, firing a crossbow bolt. The author chose a violin deliberately, as the character was working as hitperson for the Troll crimelord Chrysoprase, to spoof 1930's tropes of the killer taking an unexpected tommy gun out of a violin case to play the music with.

[[folder:Films -- Animated]]
* Disney's ''Disney/BeautyAndTheBeastTheEnchantedChristmas'' has BigBad Maestro Forte. The enchantment turned him into an OminousPipeOrgan, and [[spoiler: he literally tries to bring the house down when his plan to put a wedge between Belle and the Beast fails.]]
* ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'' climaxes with a ''literal'' battle of the bands between the Dazzlings and the Rainbooms (plus Twilight Sparkle, [[spoiler: Sunset Shimmer, and DJ Pon-3]]), with the two sides firing blasts of MagicMusic at each other.
* Sour Note from ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'' is a weaker version of this: the loud, shrill sound waves from his clarinet are able to send people running, but Burger Beard holds the fort.
* ''WesternAnimation/YellowSubmarine'': "They hate music that much, do they?" "They shrink at the very sound!"
* The Pied Piper in ''Film/ShrekForeverAfter'', whose flute lets him control other creatures (mainly making them dance uncontrollably and go in a certain direction), hires himself out as a bounty hunter.

[[folder:Films -- Live-Action]]
* The blind musicians (well, only one of them was blind) in ''Film/KungFuHustle'' can tear people apart with their music, [[RazorWind in the form of invisible blades and fists]], and at the height of their performance they're summoning hordes of Chinese zombie warrior ghosts out of their instruments.
* ''Film/WildZero'' features real-life Japanese rock band Guitar Wolf fighting hordes of aliens and zombies with homing guitar picks, samurai swords in the necks of their guitars and the pure [[ThePowerOfRock POWER OF ROCK AND ROLL]].
* The low budget movie ''Film/SixStringSamurai'' [[ExactlyWhatItSaysOnTheTin sums it all up in the title]]. Most of the characters are this.
* In ''Film/ScottPilgrimVsTheWorld'' a Battle of the Bands turns literal, with Sex Bob-omb and the Katayanagi Twins blasting each other with waves of sound from their amps. Eventually those sound waves turn into a giant gorilla and a giant, two-headed dragon and fight it out over the heads of the audience.
** Lets not forget the bass battle between Scott and Todd where Scott [[spoiler:gets blown through three walls by the power of Todd's bass. He winds up landing in a coffee shop where he tricks Todd into drinking half and half, sapping him of his vegan powers]].
* In ''Film/ThePunisher2004'', Frank has to face a hitman by the name of Harry Heck in one scene. He first sees Heck in a diner as the man sings and plays what appears to be an original song and is then informed, "I'm gonna play it at your funeral". He waits until the vigilante leaves the diner before trying to kill him and never incorporates his guitar in his actual killing.
* In ''Film/HocusPocus'', the witches sing a catchy VillainSong in an attempt to enchant a room of partygoers into dancing themselves to death.

* In Creator/IsaacAsimov's ''Literature/{{Foundation}}'' series, the character of [[spoiler:The Mule]] has psychic abilities that can essentially destroy people's mentalities, often aided with an instrument called a Visi-Sonor. He can "aim" the music to cause life-threatening depression, and does.
* In Creator/AlanDeanFoster's ''Literature/{{Spellsinger}}'' series, the main character is a man sucked from his own world into one where animals are big and can talk. There, he finds out that he can do magic by singing about what he wants. God of Thunder would probably result in an awesome incendiary finish to his enemies. Guess what Pink Floyd's Money generates.
* In Creator/SimonRGreen's ''Literature/{{Deathstalker}}'' books, there's the rogue [[ImplacableMan Investigator]] Topaz, of the "Siren" class of esper, who kills by singing. She took out the ''five hundred men'' chasing her with one song.
* Creator/MichaelMoorcock's [[Literature/TheCorneliusChronicles Jerry Cornelius]], who features in various stories (including team-ups with Elric, Jimi Hendrix and the Sex Pistols) is always described as a Musical Assassin.
** In particular, Creator/NormanSpinrad's Jerry Cornelius short story "The Last Hurrah of the Golden Horde" arms Jerry with an electric violin with built-in amps which made the high notes ultrasonic, the low notes infrasonic, and the audible frequencies suppressed. When Jerry pops in his earplugs and plays various songs (ranging from "Wipeout" to "God Save the Queen") weird things happen to the minds of his audience.
--->Seven hundred chanting kindergarten children achieved satori and began to eat a huge American flag drenched in soy sauce.
* In Creator/TerryPratchett's ''Literature/{{Discworld}}'' each Nac Mac Feegle clan has a bard known as a Gonnagle whose music/poetry is so terrible that it can be used as a weapon. Fortunately for the Feegles, the Discworld has never heard of the Geneva Convention, since Gonnagle songs would likely be classified as war crimes under it.
** The [[UsefulNotes/{{Wales}} Llamedosians]] had terrible feared battle-choirs whose singing could decimate enemies and win wars. (A ShoutOut to ''Film/{{Zulu}}''). They also had battle-harps whose tones could cause walls to fall and enemies to [[BrownNote embarrass themselves]].
** Also, the enforcers of the Guild of Musicians. They have to be musicians, else they would not be in the guild, but they tend to be of the... percussive variant. And they do [[AssShove creative things with the instruments of unlicensed musicians.]]
** And Death can kill all of reality with a single, well-played strum.
* ''Literature/TheLaundryFiles'' by Creator/CharlesStross has (from book #2 on) an assassin codenamed CANDID. She bears an "Eric Zahn Special," a violin specially built [[PoweredByAForsakenChild from the bone of twelve murder/torture victims]] and tuned to frequencies [[BrownNote human beings can hear but not mentally process]]. The case bears a sticker saying "THIS MACHINE KILLS DEMONS," and it does so exceptionally well, but it's hardly that specific... At one point she plays a "song of unbinding" on it--which, among other things, unlocks doors, breaks geases, and, when specifically focused, opens ''skin''. [[BlackAndGrayMorality Naturally,]] the above-described terror is more commonly known as our hero's beloved wife 'Mo'.
* Michelle West's Kallandras is an assassin who happens to be "bard-born". He can make people feel emotions through music, and can speak in a voice that makes anyone who hears it obey, although he doesn't like to use it.
* A Shapechanger assassin attacks Morgon in the night by playing a deadly song that takes his breath away in Creator/PatriciaAMcKillip's ''Literature/TheRiddleMasterTrilogy''.
* In the ''Literature/OldKingdom'' series, the Abhorsen uses seven bells to control and banish undead. Each bell has a different power.
** Sleeper, Waker, Walker, Speaker, Thinker, Binder, Weeper. AKA Ranna, Mosrael, Kibeth, Dyrim, Belgaer, Saraneth and Astarael. If you hear Ranna, you'll just go to sleep. If you hear Astarael, the most powerful bell, you and the wielder will be hurled deep into Death.
* In the ''Kingdoms of Thorn and Bone'' series, music written in certain modes can have a powerfully harmful effect on anyone who hears it- fatal, if played correctly. A historical EvilOverlord and EvilSorcerer, the Black Jester, was noted for assembling orchestras and choirs for this precise purpose, so skilled they could wipe out whole cities; [[EvilPrince Prince Robert]] in the present storyline is also fond of this technique, with the added bonus that he's immune [[spoiler:because he's actually undead]].
* The 'death flutes' of the Zoromen in the Franchise/DocSavage novel ''Murder Melody'' can induce either unconsciousness or death in the listener depending on the tune played.
* Erica Hayes's ''Literature/{{Shadowfae}}'' urban fantasy series features a variety of supernatural beings getting involved in a crime-ridden underworld, including vampires, [[HornyDevils succubi]] and various types of [[OurFairiesAreDifferent fae]]. In this setting, [[OurBansheesAreLouder banshees]] have magical voices that can [[MagicMusic cast spells through song]], [[MakeMeWannaShout shatter glass or physically harm/kill enemies with a scream]], and [[CompellingVoice persuade/seduce humans]]. They have [[SuperSenses supernaturally sharp hearing]], but their magic lets them filter all sounds so they are not overwhelmed by them, and the magical enhancement of their inner ear apparently also gives them perfect balance and enhanced coordination. The third volume of the series, ''Poison Kissed'', is narrated by a banshee who is employed by supernatural mobsters as a bodyguard/enforcer.
* In ''Peter and Max'', a spin-off novel of the ''ComicBook/{{Fables}}'' comic series, you have Max. His flute is imbued with enormous eldritch power, so while he wreak large-scale havoc like disease and mind control, he can also kill people individually just by playing his flute.
* Possibly played for laughs and possibly played really, really weirdly straight in Libba Bray's ''Going Bovine'' with the trumpet battles between Junior Webster and the Wizard of Reckoning, with a jazz battle literally being a final face-off between the two.
* In Jayne Anne Krentz's ''Arcane Society'' series about various types of psychic talents, book 5, titled ''Running Hot'', features a Siren, a singer who channels psychic energy through her voice. She can lightly mesmerize a large audience with lower notes, but needs to be able to sing a D, E, F, or higher to focus her song on killing a person. The Siren in question is a trained opera singer who takes out enemies of her wealthy, well-connected family.
* In Stephanie Draven's ''Siren Song'', the protagonist is an EnthrallingSiren who can control men by singing. Although the heroine does not want to harm anyone, most sirens are described as serial-killer-types who compel men to drown themselves and enjoy the feeling of power it gives them. [[spoiler: The villain is also a siren, and by singing, can even compel a man to shoot himself with his own gun.]]
* In Mercedes Lackey's ''Bardic Voices'', Rune and Sparrowhawk get trapped "underhill" by elves who force them to play for them. Rune turns the tables on them by using her fiddle to force them to dance until they drop from exhaustion, then starts playing laments to make them cry until they nearly die from depression. She threatens to keep on playing until they DO die unless they release the two of them. In her "Valdemar" books, many bards have projective empathy that can make their audiences feel the emotions of their music; although we never see any of them use it to harm or kill anyone, it is implied that a Bard with a strong enough Gift could do so.
* In ''Literature/{{Pact}}'', Johannes Lillegard, a sorcerer, uses a set of pipes as his magic implement. He uses them to exert control over rats, dogs, and children, drawing upon the Pied Piper mythology.
* When they care to, the Lanorei race in [[http://tvtropes.org/pmwiki/pmwiki.php/Literature/Eludoran Eludoran]] can use [[MagicMusic song as a weapon]]. It's potent enough that their oppressors have to [[ShockCollar collar]] and [[PowerNullifier muzzle]] them to keep it under control.
* ''Literature/JakeAndTheDynamo'': This is Magical Girl Tuneless Ramona's schtick. Both her singing and dancing are so abominable that they're essentially weapons of mass destruction. They're just as dangerous to the innocent bystanders and her allies as they are to the monsters, though.

[[folder:Live-Action TV]]
* Lorne from ''Series/{{Angel}}'' has a tendency to emit ear-piercing and glass-shattering shrieks whenever he finds himself in danger. Also, regular singing apparently causes great pain to others of his kind.
* The 60's ''Series/{{Batman}}'' series was fond of this. There was the Siren, a woman whose voice could make men do her bidding and the Minstrel, whose guitar was a weapon.
* Sweet, from ''Series/BuffyTheVampireSlayer'': "[[MusicalEpisode Once More, With Feeling]]" could use his singing to make people dance to the point where they caught fire.
* ''Series/DoctorWho'':
** An Classic Who episode, [[Recap/DoctorWhoS22E6RevelationOfTheDaleks "Revelation of the Daleks"]], featured a cannon that fired compressed rock and roll.
** An improvised musical weapon features in [[Recap/DoctorWhoS29E6TheLazarusExperiment "The Lazarus Experiment"]], when the Doctor uses a church organ to kill the MonsterOfTheWeek, who is stretching his [[JustForPun mass]] [[ShapeshifterBaggage very thin]].
* In the ''Series/FridayThe13thTheSeries'' "The Maestro", the cursed antique of the week was a music box who's melody forced the listener to dance themselves to death. Death occurred either though strain on the body or dancing into deadly situations, such as out a window.
* In ''Series/TheGoodies'' episode "The Stolen Musicians", singer Cilla Black is capable of literally 'bringing down the house' with her singing voice.
* In ''Series/{{Heroes}}'' volume 5, Emma starts out as just a deaf woman able to see sound as colors. Later, she discovers the true powers of her ability - she can [[spoiler:focus the sounds that only she can see into a devastating shockwave, and she can concentrate on people while she plays music to force them to come to her.]]
* Musical weapons are the gimmick of ''Series/KamenRiderHibiki'', where they use the ultrasonic vibrations of their music to shatter the MonsterOfTheWeek. The main Rider uses drumsticks (creating a drum on the surface of the monster), the second Rider uses a trumpet-slash-machine gun and the third Rider uses an electric guitar. All three styles are apparently relatively common among the various Oni. Another present-day Rider uses a harp, while four movie-exclusive Riders from the distant past use a flute/machine gun, a gong stuck, a triangle and a pair of cymbals.
* ''Series/KamenRiderDecade'': Decade and Diend get in on the act during the finale of the Hibiki arc of their show, each using a set of drumsticks (joined by several other Riders using trumpets and guitars) against the final monster there.
* British sketch show ''Series/ThatMitchellAndWebbLook'' featured one skit with a green clarinet that made its targets sing and dance an embarrassing truth about themselves, which its owner abuses to do whatever they want. It could only be countered by [[spoiler:a red tuba that makes you [[BrownNote shit yourself]]]].
* In ''Series/TheMiddleman'', there's a cursed tuba that anyone who hears it play will "drown in the icy waters of the North Atlantic." Naturally, there's an immortal guy who wants to play it to a large crowd.
* ''Series/MightyMorphinPowerRangers''' original weaponized instrument, the Dragon Dagger. Of course, this is more of a dagger with a flute design, so...
** Zen-Aku from ''Series/PowerRangersWildForce'' also had a dagger-flute.
** For an instrument that's not deliberately weaponized, Dr. K of ''Series/PowerRangersRPM'' plays the violin to help her with her brainstorming, and has it linked to her software so that it responds to the music played. She fended off [[TheDragon Tenaya 7]] twice with that same violin: in "Ranger Yellow Part 2", she simply lured her directly beside an amp, but in her eponymous episode, she used the playing both to deafen Tenaya and turn the room's A/C fan into a tornado machine, sucking her out of the base, to the tune of Niccolò Paganini's ''Caprice No. 24 in A Minor''.

* "The Lyre of Orpheus" by Nick Cave and the Bad Seeds:
-->Look what I've made, cried Orpheus
-->And he plucked a gentle note
-->Eurydice's eyes popped from their sockets
-->And her tongue burst through her throat
-->O Mamma O Mamma

-->O God, what have I done, he said
-->As her blood pooled in the sheets
-->But in his heart he felt a bliss
-->With which nothing could compete
-->O Mamma O Mamma

-->Orpheus went leaping through the fields
-->Strumming as hard as he did please
-->Birdies detonated in the sky
-->Bunnies dashed their brains out on the trees
-->O Mamma O Mamma
* "Broken Radio" by ItaloDisco singer Den Harrow is about alien invaders who [[WeaksauceWeakness cannot stand music with rhythm]]. It literally drives them insane. Making every portable radio a weapon.
* Music/LindseyStirling has one video, "Roundtable Rival", where she uses her violin to protect a Wild West town from guitar-wielding bandits.

[[folder:Myths & Religion]]
* OlderThanFeudalism: The Sirens in ''Literature/TheOdyssey'' sang so beautifully sailors dashed their ships on the rocks around them.
* [[Literature/TheBible God told Israelites to march around the walls of Jericho]] and shout, and sound trumpets on the seventh day. On the seventh day, the walls were breached.
* In the Swedish legend of the Hårgadance a mysterious fiddler turned up one day in the village of Hårga during a celebration and started playing a song on his violin that made everyone dance enthusiastically. Too late, the people realized that the man, who they now saw had a goat's leg, was the Devil himself. They were unable to stop dancing and kept doing so while the fiddler led them up the nearby Hårgamountain. There, he kept playing until everyone had been killed and their bodies torn to bits by the intense dancing. The top of Hårgamountain is still flat to this day because of the wild dance.
** There is also the Swedish myth of Näcken, sort of a male version of the sirens. Näcken is a nude man with long hair who sits in the middle of a raging river (or occasionally a lake) and plays the fiddle, luring people to drown with the music. There are stories about musicians who have bargained with him to learn his skill at the fiddle, but these contracts usually have a terrible prize, as Näcken is a trickster at best, and outright evil at worst.
* In the Finnish national epic Kalevala, Väinämöinen, a wise old man with the gift for magical singing. engages in a battle in the said craft with Joukahainen. Väinämöinen almost sank Joukahainen in a bog with his song, but decided to take Joukahainen's sister instead.
* The harp of the god Angus Og, in Irish mythology, held great power. It was captured in battle by the hideous troll race of the [[OurTrollsAreDifferent Fomorians]]. One night, Angus and a comrade crept into the Fomorian camp and were discovered stealing the harp back. Undeterred, Angus played the harp and even the foul trolls were overcome by the beauty of his playing. Legend has it he played the harp three times. first he played the notes of joy that caused the enemy to rejoice. Then he played the notes of sorrow that caused them to be overborne with tears. Finally he played the notes of sleep, that rendered them insensible. Thus was he able to return unscathed to the Tuatha de Danaan having won back the harp.
* Christian tradition is that evil creatures (including witches and wizards) cannot bear the sound of church bells.

[[folder:Tabletop Games]]
* In the ''TabletopGame/{{Warhammer 40000}}'' setting, 2nd edition Slaaneshi Noise Marines use sonic weapons whose destructive sound waves can tear humans and even tanks to shreds and looked like [[ThePowerOfRock electric guitars]]. It's not so much 'music' as 'flesh-rendingly loud noise', and were replaced with less fitting guns.
** There were also troops belonging to the Ork Goffs clan that wielded electric guitars. Their name? Goff Rockers, of course.
** And on the [[BlackAndGrayMorality 'good']] side, we have the [[TankGoodness Exorcist]] of the [[AmazonBrigade Sisters of Battle]], the holy fusion of a MacrossMissileMassacre and a ''pipe organ''.
** In the background novels of the "Literature/HorusHeresy" series, the Space Marines encounter Warsingers, leaders of a xeno race who use their song (literally) to kill even [[SuperSoldier Astartes]] with lethal swiftness. Their song was described as serenely intoxicating.
** Lets not forget Eldar Bonesingers, who use music to shape 'psychoreactive' wraithbone into a variety of weapons and tools. Their songs may not be literally lethal, but the gravitic induction shuriken launcher they just sang out of a lump of plastic is.
** There was a 3rd-ed upgrade for Chaos vehicles attached to Noise Marine units which would give them similar abilities, by having speakers and organ pipes sprouting from all over the vehicle.
* ''Tabletopgame/{{Exalted}}'' wouldn't be a proper anime-based RPG if it didn't have one of these (it's a Dragon-blooded Performance charm, natch). The Abyssals also have a Performance charm that can deal damage, and there's a [[MartialArtsAndCrafts Celestial martial arts style]] based on this trope: the Silver-Voiced Nightingale Style.
* ''TabletopGame/DungeonsAndDragons'':
** The Bard from can hypnotize people with a musical performance, and there are prestige classes in Third Edition that will let him summon fire or lightning with the sound of music. Bardic songs are also good for debuffs.
** Not to mention multi-classing into Rogue or Assassin in 3e/3.5/Pathfinder. Then it's a bit more literal. Fascinate and Death attack can be a killer combo.
* The ''TabletopGame/{{Pathfinder}}'' bard's highest level ability is called "Deadly Performance". Hear or see the bard perform and fail your save and you die, either from joy or sorrow.
* ''TabletopGame/WeaponsOfTheGods'' has a martial arts style called Music of War which lets you attack and debuff enemies from a distance by playing a musical instrument.

* B-Flat Bart from Peter Schickele's ''Hornsmoke: A Horse Opera'', who appears to mow down the rest of the cast (all of them musicians) with his trumpet.
* Schunard in ''Theatre/LaBoheme'' is hired to play his violin to a parrot until it dies. It works.
* ''Theatre/{{Rent}}'', which is based on ''Theatre/LaBoheme'', features a similar plot point, with Angel (Schunard's equivalent) playing his drums (pickle tubs) to a rich woman's neighbor's dog in hopes that it will die. The dog eventually jumps from the window ledge of a twenty-third story apartment.

[[folder:Video Games]]
* One of the many [[RuleOfFunny frankly insane]] weapons in the ''WesternAnimation/AquaTeenHungerForce'' spin-off golf/combat game, [[NinjaPirateZombieRobot Zombie Ninja Pro-Am]], alongside the {{chainsaw|Good}}, golf club and sword, is the Red Electric Guitar. Rather than hitting your opponent with it, you can stun and injure enemies ranging from [[ThisIsYourPremiseOnDrugs malevolent walking adjustable spanners]] to robot turkeys from the future, and even pull off a 360 of destruction by charging it up.
* A newly-added class in ''VideoGame/AtlanticaOnline'' uses a guitar as a weapon. Despite very obviously being an acoustic guitar, it makes electric guitar noises, likely because of RuleOfCool. The same reason there's a class that uses what appear to be modern chainsaws in an apparent pre-20th-century AnachronismStew setting -- there were Chainsaws in the 19th century, but they don't look anything like what a modern viewer would expect.
* Lyude from ''VideoGame/BatenKaitos: Eternal Wings and the Lost Ocean'', used a type of weapon called a "sound shock gun", which was something of a cross between a trumpet (or other instrument) and a machine gun. Oh, and all of his finishing moves were musical terms.
** A particularly conspicuous card for Lyude: "Assault Trumpet". Description: "Designed for covert use by assassins."
* As the above quote suggests, ''VideoGame/BrutalLegend'' loves this trope. [[RuleOfThree Three]] people have electric guitars that they can play to use magical attacks: Eddie Riggs, [[spoiler:Drowned Ophelia]], and [[spoiler:Emperor Doviculus]]. Also, the Drowning Doom's Organist unit plays a funeral dirge that weakens enemy troops while Ironheade's Thunderhog plays bass riffs to heal wounded allies, and General Lionwhyte's metal screams can shatter glass and mirrors.
** It's worth pointing out that in combat, Eddie has access to both combos featuring guitar chords that create effects anywhere from lighting to fire to actual stage pyrotechnics, as well as powerful solos that create numerous battle-changing abilities--particularly one that literally [[ThePowerOfRock melts faces off of nearby enemies]].
** Also, the Roadies of Ironhead can destroy enemy buildings by blasting them with sound waves from the giant speakers they carry, and the Rock Crusher buffs friendly units with ThePowerOfRock.
* ''VideoGame/CaptainSilver'' has the [[Literature/ThePiedPiperOfHamelin Pied Piper]] in Stage 1, who attacks by summoning rats with his music. In the Sega Master System version, he also directly attacks with musical notes.
* One of the bonus weapons in ''VideoGame/CastlevaniaCurseOfDarkness'' is a badass looking skull guitar that would make metalheads envious. Hector attacks by RAWKIN' OUT DOOD! The screen shakes and vibrates for every uninterrupted riff he plays, though some larger enemies aren't staggered by the playing, ditto for those which can move underground or 'phase out.'
* ''VideoGame/ChronoCross'' had Nikki. His weapon was, of course, a guitar (the guitar ''pick'', if you wanna get technical), and his basic attack was playing it. His first special was to bludgeon someone with it, Hendrix-style.
** Irenes did something similar with her harp. And of course, there's bunnygirl Jan, who beats on a drum with a carrot.
* The Musician in ''VideoGame/CitizensOfEarth'' can use one of three musical attacks. Each has a different duration, and the attack's damage output increases for each turn.
* ''VideoGame/{{Cocoron}}'', a Japanese only video game, in which you build six characters to play as, including the weapon they use. One of the weapons is musical notes, and the characters generally launch their attacks from their heads. LetsPlay/DeceasedCrab, Website/YouTube celebrity, made this famous through his Let's Play of the game, with the third character he made being Tasian, the Singing Ninja Tank. ''''.
* ''VideoGame/CommandAndConquerTiberiumWars'' has the sonic emitter as the GDI's high tier defensive structure, which is basically a gigantic loudspeaker. In the expansion, the weaker but mobile version is also available, known as the Shatterer.
** ''[[VideoGame/CommandAndConquerTiberianSun Tiberian Sun]]'' also has the sonic tank, which is the prototype of the above-mentioned weapon.
* ''VideoGame/{{Darkstalkers}}'' has Lord Raptor/Zabel Zarock, who has a guitar counter-attack, in addition to looking like a zombie rocker.
** From the same game, Lilith also has a special, the Gloomy Puppet Show. When the move input is completed, she tosses a top hat at the opponent. If it connects, she switches outfit, while the opponent is put upon a makeshift stage. A mini-game then starts, where you need to tap the right keys in the right rhythm. Depending on how well you perform, the opponent could take massive amounts of damage, or very little.
* The BigBad of ''Videogame/DeathSpank'', Lord Von Prong, uses singing as a smart bomb (and at the end of first act of the game, [[BigLippedAlligatorMoment ends all of his sentences with a falsetto high note]]). ''Why'' he uses singing as a power despite being otherwise a generic evil knight, [[MST3KMantra like many other things in the game]], is never explained.
* In ''VideoGame/DevilMayCry 3'', Nevan, a [[HornyDevils succubus]] boss character, [[http://www.youtube.com/watch?v=oskw8aGIFk0 becomes an electric guitar]] after you defeat her as Dante. She is arguably the most difficult to use yet most powerful weapon in the game, easily allowing [[RankInflation SSStylish]] combos if used properly. It electrocutes enemies by shooting lightning at them and summoning bats to attack them.
* In ''VideoGame/DonkeyKong64'', each character could obtain a musical instrument that could be used as a limited-ammo special attack to destroy nearby enemies (Donkey Kong got bongos, possibly inspiring his final smash in Super Smash Bros. Brawl).
* A mod for ''VideoGame/{{Doom}}'' lets you use [[http://www.youtube.com/watch?v=8aJjMOy-Ops the Rick Roller]], a stereo that plays "Never Gonna Give You Up" and deals more damage than the BFG. Not even doom monsters can withstand RickRoll!
* ''VideoGame/Drakengard3'' has a an "Intoner mode" that powers up all of your attacks and adds vocals to the music. The bosses also have same ability, letting them sing and create devastating attacks.
* ''VideoGame/{{Dubloon}}'' features the Quartet of the Seas, [[JustForPun a band]] of {{four|IsDeath}} {{bonus boss}}es, [[HurricaneOfPuns composed of]] a rapper Vypa, guitarist Standish, flutist Captain FC and a pianist Sparkles.
* Zhen Ji in ''VideoGame/DynastyWarriors'' (except the sixth installment) uses flutes for sound waves. In 7, she is joined by Cai Wenji, who uses a harp.
** Sister series ''VideoGame/SamuraiWarriors'' has Motochika Chōsokabe, who wields a shamisen (a Japanese guitar, more or less).
* How Sweety Belle works in the ''VideoGame/EarthBound'' [[GameMod ROM Hack]] ''VideoGame/EquestriaBound''. Her main weapons are ''microphones'' and she uses MagicMusic as oppose to PSI.
* ''VideoGame/EphemeralFantasia'' may as well be called [[VideoGame/GuitarHero Lute Hero: The RPG]] as a lot of story segments require you to play along, for serenading your girls, to annoying the main villain. Sadly, in normal combat, you just pull a sword from the spine. Music instead takes the place of healing and support magic, and the occasional song-related attack spell. The hero plays these automatically though.
* ''VideoGame/EternalFighterZero'' has Mizuka Nagamori, who can create exploding music notes with her cello.
* The Bard class from the various ''Franchise/FinalFantasy'' games uses a variety of instruments, the most popular of which is a trusty harp. Sometimes they induce StandardStatusEffects, but the chances of doing so are very low. Because of this, they're often also a QuirkyBard.
** In ''VideoGame/FinalFantasyV'' songs are extremely effective, when used right. One of them causes massive damage to undead, for example. Another can consistently cause confusion to the right kind of enemies.
** ''VideoGame/FinalFantasyIX'' plays with this. Eiko's weapon class is a flute that she hits people with it for her standard attack. The real reason she has it is to do Summon Magic. She's a WhiteMagicianGirl.
** Also subverted in this manner in ''VideoGame/FinalFantasyTacticsAdvance'' and ''VideoGame/FinalFantasyTacticsA2'', where the Beastmaster, Animist, and Bard classes all equip musical instruments such as flutes and harps to learn appropriately musical and monster-based skills (Music Soothes the Savage Beast, get it?), but when used in an attack, the unit in question simply brains the enemy with it (Kabong!). Suddenly, the descriptor from ''VideoGame/FinalFantasyTacticsA2'', "Ill-tuned Instruments", makes much more sense.
*** The original Final Fantasy Tactics (subtitled War of the Lions because of the GBA sequels) also featured bards. Their songs either affected every ally with a positive or every enemy with a negative effect.
* Also by Square Enix, the IOS game Song Summoner. The Hero LITERALLY fights with music - that the player actually has on their device. You can even level your songs up by listening on them often.
* ''VideoGame/GodHand'': one of the bosses is a guitarist. With lightning projectiles. And he has a return battle where he pulls in a drummer, too.
* I-No from ''VideoGame/GuiltyGear'' is armed with a guitar and knows how to use it. Explosive notes are the weakest of her weapons. Her ultimate attack, Megalomania, projects horrifically powerful bursts of sound from a pair of miniature amplifiers.
* In ''{{VideoGame/Gungrave}}: Overdose'', the rockabilly Rocketbilly Redcadillac [[NamesToRunAwayFromReallyFast (yes, that's his name)]] implies that he was once one of these assassin types. Now, though, he's TheAtoner and a ghost, possessing an electricity-shooting guitar.
* In ''VideoGame/Halo3ODST'', there is an achievement (Vidmaster Challenge: Classic) for completing a level without firing a weapon. Beware: tooting vehicle horns counts.
* ''Franchise/KingdomHearts'':
** The iconic example in the franchise is found in ''VideoGame/KingdomHeartsII''. Organization XIII's number IX, the BrilliantButLazy [[MakingASplash water-manipulating]] "ThatOneBoss" sitar player, Demyx. One of the reaction command moments in the fight has him playing away, seemingly completely oblivious to Sora, who looks like he is either preparing an attack or [[SugarWiki/FunnyMoments trying to get his attention]]. But that's the extend of taking him lightly; anyone who faces him dreads hearing his CatchPhrase: "[[TimedMission DANCE, WATER, DANCE!]]"
** ''VideoGame/KingdomHeartsBirthBySleep'' gives us the Symphony Master Unversed, which not only attacks with its conductor baton, but also controls a floating trumpet, violin '''''and''''' drum at the same time.
** The Necho Cat and Frootz Cat dream eaters in ''VideoGame/KingdomHearts3D'' mix this with DanceBattler, launching various types of painful musical notes (Like exploding f-minors) with elements or StandardStatusEffects attached to them by dancing.
* The Accordion Thief of ''VideoGame/KingdomOfLoathing'' have various accordions as weapons, and as of a class revamp in late October 2013 they gained a variety of combat skills using their accordions. There are also many, many instruments -- [[http://kol.coldfront.net/thekolwiki/index.php/Player_Hit_Messages accordions, banjos, drums, guitars, flutes, horns, and one axe-type weapon]] -- which have hit messages that are this, InstrumentOfMurder, subversions or double-subversions of either/both.
** The Accordion Thief's nemeses, the Mariachis, are NPC examples, though players can wear their clothing and equip their musical weapons.
* Sona, the Maven of the Strings from ''VideoGame/LeagueOfLegends'' attacks by firing waves of sound from a guzheng-like instrument. She can also amplify her attacks by playing songs, send out discordant waves of sound to hunt down opponents, and her ultimate ability forces opponents to dance to her song while their health drains.
** Not only this, but if you play Sona as APC on the midlane (have luck finding a team that doesn't bash you for it though) and you build Lichbane on her, you can pretty much kill other squishy champions with two repetitions of her Q-Q-Q-Autoattack+Lichbane proc.
* In ''VideoGame/LollipopChainsaw'', each member of the [[QuirkyMinibossSquad Dark Purveyors]] represents a style of music in their fighting style and uses it to power their magic.
** Zed represents PunkRock and fights with a LaserBlade mike-stand and [[WordsCanBreakMyBones weaponized profanity]].
** Vikke represents Viking Metal, along with being an actual Viking, and fights with an axe and [[ShockAndAwe lighting]].
** Mariska represents PsychedelicRock, along with being a hippie, and fights with drugs and "real" illusions.
** Josey represents {{Funk}} and fights with lasers and weaponized video games.
** Lewis Legend represents RockAndRoll and fights with [[InstrumentOfMurder a guitar with a concealed machine gun]] and a CoolBike that can transform into an elephant mecha.
* ''VideoGame/LordOfTheRingsOnline'': Not an assassin per se, but the Minstrel class uses instruments and voice to deal respectable damage.
* In ''VideoGame/LuminousArc2'', the Brilliant Witch, Dia, uses a conducting baton as a weapon. Kaph, who later joins the party, subverts this trope with a guitar...[[InstrumentOfMurder that fires bullets]] (one of his best weapons for illustrating this trope is the Keyguntar, which is one-third keyboard, one-third gun, and one-third guitar). Also, Sadie uses horn as her weapon, and actually has a spell to emphasize on that fact.
** Amusingly, Dia is rumored to be tone deaf, and Sadie has to play badly to do any damage - she can play well, but that only stirs up a light breeze. Meanwhile, the guy who doesn't actually play an instrument on the field is a multi-talented and highly respected artisan.
* The pink-haired mini-bosses from ''VideoGame/MagicalCannonWars'' use their guitars as weapons and their bullets are music notes.
* Vulturon the Condoroid of ''VideoGame/MegaManZX Advent'' is capable of repulsing melee attacks (and even some ranged attacks), discharging waves of scrap parts, and animating defunct Mechaniloids. While these do sound like ordinary powers to many a medium, what makes it noteworthy is that he does it all...with power chords. He also occasionally simply swats you with his guitar. (His Japanese name is Condorrock the Vulturoid. Go figure.)
** Tech Kraken of ''VideoGame/MegaManZero 4'' did something of the sort. At least, one of his attack calls is "Sound...dance!"
** Harp Note from ''VideoGame/MegaManStarForce''. Contrary to her name, her weapon is more like a guitar.
** Shade Man's Noise Crush in ''VideoGame/MegaMan7''.
* The Pop Stars in ''VideoGame/{{Miitopia}}'' can use their voice to inflict damage upon their enemies. Their WeaponOfChoice is a microphone.
** Then there is the Rock Hopper enemy, a [[BuffySpeak weird, big-lipped, pink... thing]] that plays it's electric guitar to damage the Miis.
* ''VideoGame/MonsterHunter'' games of late have adopted a Hammer subclass called the Hunting Horn, which induces StandardStatusEffects by entering what's called Recital Mode, and then pressing attack buttons to play different notes. Different note combinations got you different effects. In a nice change of pace from your standard self-buffing classes in an action-RPG, they're also good for clocking a monster over the head without a Recital beforehand.
* The whole battle system of ''VideoGame/{{Mother 3}}'' revolves around Rhythm Combos. If you select your basic attack and press the A button to the beat of the music, you can link together combos. Almost every enemy has their own special song to combo to.
** Also, whenever you do hit the enemy, each playable character has a different kind of musical note played upon attacking. (Flint = Saxophone, Duster = Bass, etc.)
** [[spoiler:New Fassad (and Miracle Fassad)]] also counts, using off-key music as an attack.
* The [[OurAngelsAreDifferent Archon]] from ''VideoGame/NexusClash'' can sing the Song of the Word, which harms any being not sufficiently holy to hear and understand it. Some Archons may have ''dramatically'' different interpretations of just who is and is not holy enough to hear their particular Song unharmed.
* There's a mod for ''VideoGame/NeverwinterNights2'' actually called Lute Hero. It makes you play a VideoGame/GuitarHero style rhythm game which is used to power your spells in combat. [[http://www.youtube.com/watch?v=6n0vmCqv5yo It has to be seen to be believed.]]
** In the original campaign, Bards have a variety of songs. While most of it is just buffs or debuffs, the ultimate song, Hymn of Requiem, is a very nasty attack that deals sonic damage (which is unavoidable) that is twice your Perform skill to either one enemy, or splits it across multiple enemies...and then ''[[LifeDrain heals your whole party by the amount of damage dealt]]''. It does this every turn for five turns (ten if you took the Lingering Song feat). QuirkyBard the PlayerCharacter is not.
* Kurow in ''VideoGame/{{Okamiden}}'' attacks by playing his flute, at which point damaging music notes come out of it. [[spoiler:He uses it [[InstrumentOfMurder differently]] in the boss fight against him.]]
* ''[[VideoGame/{{Onmyoji}} Onmyōji]]'': Yōkinshi who kicks ass with style using the sound of his ''guqin''.
** Kochō-no-sei and her tambourine is a much cuter example, but no less dangerous.
* The main character in ''{{Otocky}}'' collects musical notes which he then uses against large boss notes.
* ''VideoGame/PlantsVsZombies2ItsAboutTime'' has the Hair Metal Gargantuar. During a [[ThemeMusicPowerUp Metal Jam]], his guitar smashes cause sonic music shockwaves that travel the lawn and decimate the first plant it hits.
* ''Franchise/{{Pokemon}}''. Sure, all that Sing does is put the opponent to sleep, but there's always Perish Song, which kills anyone who hears it within three turns. Not to mention Hyper Voice, Bug Buzz, and other sound-based attacks. [[http://bulbapedia.bulbagarden.net/wiki/Meloetta And then there's Meloetta.]], a Mythical Pokémon who uses mostly sound-and-music-based moves; and [[OurMermaidsAreDifferent Primarina]], a siren who controls water through singing and whose Hidden Ability, "Liquid Voice," turns all sound-moves into Water-type moves.
** There's enough sound-based moves to warrant the Soundproof ability (which blocks them outright).
* Cornet from ''VideoGame/RhapsodyAMusicalAdventure'' uses her horn as a weapon, although it's more often the channel through which she controls her helpful puppet/monster friends.
* Bards in ''VideoGame/{{Rift}}'', who usually use their assortment of instruments to buff allies, can also strum their lyre to channel a damaging cadence.
* Yurika Kirishima from the ''VideoGame/RivalSchools'' sequel ''Project Justice'' is a subdued variant, her signature weapon being a violin.
** Her ManipulativeBastard brother Kurow is also an example, using his flute to brainwash victims.
* ''VideoGame/SaintsRowIV'' has a dubstep gun firing exploding wubs that may be a ShoutOut to the below Corridor Digital video.
* Apollo in ''VideoGame/{{Smite}}'' takes the title of 'God of Music' and aside of attacking with finger bolts, his skills involve about weaponizing his singing voice or playing his lyre to damage the enemy. He's a Hunter-class God, so he's more likely to 'assassinate' some oppositions with his music.
* The ''VideoGame/{{Suikoden}}'' series also have this trope. Particularly the [=DoReMi=] Elves that attacks by singing a note, and Cornelio in ''VideoGame/SuikodenV'' who uses ''[[ImprobableWeaponUser a conducting baton]]''.
* ''VideoGame/SuperSmashBros. Brawl'' has several. Donkey Kong uses bongos for his final smash (the damage and range of which depend on your rhythm); an assist trophy plays guitar; [[Franchise/{{Pokemon}} Jigglypuff]] and [[Franchise/SuperMarioBros Peach]] put enemies to sleep with song; Luigi uses a dance number to summon the Negative Zone; and King Dedede has a [[strike:song and dance summon]] [[FanNickname Big Gay Dance]].
* Episode 1 of ''VideoGame/TalesFromTheBorderlands'' features a music-obsessed bandit chief named Bossanova, who can fire blasts of amplified techno and dubstep from the speaker mounted on his armor.
* In ''VideoGame/TalesOfTheAbyss'', Tear Grants makes her first appearance by singing all the guards in Luke's house to sleep so she can get in and assassinate Van. All of her highest level fonic artes, including a couple of very powerful magical attacks, are cast by singing the [[MagicMusic Yulian Fonic Hymns]].
* ''VideoGame/TheLegendOfZeldaMajorasMask'' gives us Sharp and his Melody of Darkness, which slowly drains [[HeroicMime Link's]] health away.
* ''VideoGame/TheNightmareBeforeChristmasOogiesRevenge'' has an attack that is nothing more than Jack singing and dancing, but shoots musical notes at the enemy that are devastating compared to Jack's normal attacks. In fact, this is the only way you can defeat the final boss (and is even powerful enough to summon giant balls of snow to rain from the sky and fire to shoot from the ground).
* ''VideoGame/{{Touhou}}'' doesn't have just one of these, it has ''6''.
** The Prismriver Sisters, a trio with each one associated with a different instrument. In the ninth game, their EX attacks involve them sending over their instrument to your side and having it launch bullets at you.
** The fourteenth game adds the Tsukumo Sisters and Raiko Horikawa, each with a different of their own.
* The whole point of ''VideoGame/SpaceChannel5'' and its sequels.
** Also the whole point of ''VideoGame/GitarooMan''.
* Most of Achmed Khan's special moves in ''VideoGame/BackyardSkateboarding'' live off this trope (and an AirGuitar).
* One ''WesternAnimation/SpongebobSquarepants'' game allows him to play a guitar riff so awesome that its sound is a guided missile.
* The entire plot (such as it is) of ''VideoGame/LegoRockBand'' is that your band uses the power of music to achieve everything from fighting off a monstrous squid to obliterating an asteroid on it's way to hit the planet.
* The Atreides in ''VideoGame/DuneII'' have the Sonic tank, a tank which 'fires' sound waves to destroy everything in its path.
* The "Devil's Wind" music on the 12th floor of Darm Tower in ''VideoGame/{{Ys}} I'', which drains your HP.
* The Guitar Warrior from ''VideoGame/TotalDistortion'' (illustrated atop GameOverMan).
* The giant Punk Rocker from ''VideoGame/MonsterParty''. "[[{{Pun}} Face the music!]]"
* Elite Tauren Chieftain (ETC) in ''VideoGame/HeroesOfTheStorm'', named after a Warcraft-based band, is basically a Tauren who's a rockstar and his moveset is basically utilizing his electric guitar-axe hybrid to send shocking melodies to the enemy for various effects.
* VideoGame/HyruleWarriors has Sheik, who uses a harp which generates both sonic shock waves and various elemental attacks. Zelda, who can use a conductor baton that shoots electricity and wind. Skull Kid who uses an ocarina to command both [[FairyCompanion Tatl and Tael]] as well as sinister puppets. Medli, whose harp shoots air blasts and light energy and Marin who uses a bell that shoots water as well as being able to summon the Wind Fish.
* Lúcio froom ''VideoGame/{{Overwatch}}'' fights his enemies and supports his team-mates through [[DiscoTech various sonic-based devices]]. He'll also be joining the aforementioned ''VideoGame/HeroesOfTheStorm'' where he will also bring ''debuff'' music instead of just buffing music.
* ''VideoGame/{{Warframe}}'' has Octavia, whose abilities can damage enemies and provide buffs to teammates while playing parts of player-composed songs.

[[folder:Web Animation]]
* The episode "Never Miss A Beat" from ''WebAnimation/{{RWBY}}'' introduces Flynt Coal, a Huntsman student modeled after a jazz musician who fought with a trumpet that could create large sonic blasts.

* ''Webcomic/SoulSymphony'':
** Protagonist Olivia's weapon of choice against monsters is a clarinet allows her to fly and create magical shields, among other things. Once [[spoiler:John]] joins her in the fray, he uses a trombone as a sword and a cannon.
** In Movement 2, [[spoiler:the giant Gnarlequin that acts as the 'boss' of Charlie's soul attacks John and Olivia with soundwaves from a giant electric guitar.]]
** In Movement 4, [[spoiler:Ashley's embodiment of Tom Mustaine in her Soul World also attacks with electric guitar strums.]]
* ''Webcomic/GuildedAge'': Payet, if you can call fighting with a half-instrument half-axe killing with music.

[[folder:Web Original]]
* Midgard of the Counterfactual.net crew from ''Script/AHDotComTheSeries'', who once destroyed a civilisation with the right power chord.
** And later, The King.
* In the ''Roleplay/GlobalGuardiansPBEMUniverse'', superheroes The King, the [[AnthropomorphicPersonification Anthropomorphic Incarnation]] of the popular image of Elvis Presley, and Crescendo can both belt out [[MakeMeWannaShout songs]]. The King uses Rock-n-Roll, while Crescendo sings opera.
* In ''Literature/SuperStories'', the Host weakens and hurts his opponents with music. His partner, Cabaret, is immune.
* In the Corridor Digital video [[http://www.youtube.com/watch?v=hDlif8Km4S4 Dubstep Guns]] this trope is combined with [[FrickinLaserBeams some lasers]] for interestingly devastating results.
* Siren from ''Literature/{{Phaeton}}'' can manipulate both people and the universe with music, she also has a weapon/instrument that doubles as an instrument/weapon. No one is entirely sure which it is and which it doubles as though.
* [[http://www.scp-wiki.net/scp-298 SCP-298]], a pipe organ which will expel blood right out of the audiences' bodies.
* In ''WebOriginal/ArknLegacy'', Ryael from Bard of the Black Violin almost certainly counts for this trope. In their Arkn life, it was mentioned they had killed with the powers of the titular Black Violin.

* ''WesternAnimation/BatmanTheBraveAndTheBold'' has fan-favorite [[Creator/NeilPatrickHarris Music Meister]] who uses his singing voice to hypnotize his victims. He doesn't need to kill people with his voice, as he can easily order them to kill themselves by dancing into a rocket blast.
* ''WesternAnimation/BikerMiceFromMars'' has Hard Rock from the episode of the same name. While reformed prior to the series' start, a flashback in the episode shows that when he was still a minion of the Plutarkians, he leveled entire cities on Mars just by playing his guitar.
* Ember [=McLain=] from ''WesternAnimation/DannyPhantom''. Her guitar is her main weapon.
* Floatzart, whose music could control ghosts in ''WesternAnimation/FilmationsGhostbusters''.
* In ''WesternAnimation/GIJoe'', Metal-Head was capable of destroying a skyscraper with the amplified sound of his metal music.
* The 1929 ''ComicStrip/KrazyKat'' short ''Ratskin'' (the first one with sound) features an Indian shooting arrows at Krazy. He retaliates by using the arrows to create a makeshift harp, playing it to produce musical notes and firing them at the Indian.
* An interesting twist is the old ''WesternAnimation/LooneyTunes'' cartoon "WesternAnimation/NowHearThis", in which a man finds a 'horn' which creates strange and magical (and which would be violent in other circumstances) occurrences throughout the 'toon. In the end it turns out to have been the devil's horn! He screws it back onto his head and explodes away, leaving the man in confusion.
* There's a villain in season 2 of ''WesternAnimation/LoonaticsUnleashed'' with this power.
* Coop in ''WesternAnimation/MegasXLR'': "[[TimTaylorTechnology Re-routing all power to... the Jammer]]."
** Note that The Jammer is considered to be ''the most lethal weapon on Megas.'' It has more systems preventing its use than anything else.
* In the second season finale of ''WesternAnimation/{{Metalocalypse}}'', [[spoiler:the Revengencers attack Mordhaus, first disabling its defensive forcefield with sonic weaponry]]. [[BloodyHilarious Dethklok themselves]] are also quite capable of using ThePowerOfRock in a fight.
** Dethklok also punishes anyone [[DigitalPiracyIsEvil who pirates their music]] by kidnapping them within seconds of the download completing and imprisoning them in a room surrounded by hundreds of speakers which constantly blast Dethklok songs at an extremely high volume to torture them. Hey, [[BeCarefulWhatYouWishFor they wanted to listen to Dethklok's music for free]], didn't they?
* "Music Land", a 1935 Disney Silly Symphonies short, features a Romeo and Juliet-esque romance between the saxophone prince of the Isle of Jazz and the cello princess of the Land of Symphony, and briefly leads to a literal musical war between the parents of the couple.
* Variant: ''WesternAnimation/QuickDrawMcGraw'''s alter-ego El Kabong uses a guitar as his weapon. KABONG!
* Bluegrass and Melodia are opposing musical assassins on ''WesternAnimation/SilverHawks''.
* The Rat King in the first ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' cartoon use a flute to control rats, including the turtles' master Splinter.
* Soundwave from ''WesternAnimation/TransformersAnimated''. He uses Laserbeak and Ratbat as a powerful electric guitar and keytar respectively.
* An episode of ''WesternAnimation/WanderOverYonder'' features a musical [[BeamOWar Beam-O-War]] between [[AllLovingHero Wander]] with his banjo and [[NotSoHarmlessVillain Dr. Screwball Jones]] and his accordion in the middle of the latter's VillainSong. One of the strings on Wander's banjo breaks and [[NoHoldsBarredBeatdown Screwball lets him have it]]!
* Scaramouche from Season 5 of ''WesternAnimation/SamuraiJack'', who initially uses a [[MagicalFlutist magic flute]] to [[MindOverMatter telekinetically]] move rocks and create a [[ImprovisedGolem gigantic stone golem]] to fight Jack with. When the flute is broken, he uses {{scat}}ting to swing around a scimitar instead. He also has a tuning fork (or perhaps a reverse tuning fork) that causes objects it hits to vibrate until they explode. He destroys both of Jack's DualWielding daggers in this way, but Jack takes the tuning fork from Scaramouche after defeating him.
* In the {{Creator/Pixar}} short "WesternAnimation/SanjaysSuperTeam", a Hindu goddess rings a prayer bell in order that the sound waves it emits might kill an attacking monster. [[spoiler:This attack fails, but Sanjay then uses the prayer candle holder as a bell, and this succeeds.]]
* Wufgang Bark, from the ''WesternAnimation/DangerMouse'' episode "Play It Again, Wufgang," has stolen all the music in the world (including the episode's background music). He manipulates it from a pipe organ, causing DM and Penfold to lapse into slapstick when he plays the bridge from Spike Jones' "Cocktails For Two."
* While we only meet him in a [[TheStinger stinger,]] Concerto in ''WesternAnimation/RickAndMorty'' qualifies.

* There is a sonic projector called LRAD which can put out incapacitating noise up to 1000 feet from the device.
