->''"The Red Flag: nice tune, shame about the words."''

So you've got some lyrics. They're wonderful, they're catchy, but you just can't seem to come up with the right music...

Hey, why not just put it to the tune of an older song?

One of TheOldestOnesInTheBook, as many, ''many'' traditional songs and national anthems do this. This can produce a [[LyricalDissonance very dissonant effect]] if the two songs have completely different moods. It's also common in hymnody; most traditional hymnals include the meter signature for each text so it can be easily matched to other tunes; e.g., CommonMeter ( -- used by AmazingFreakingGrace and many others).

Among music scholars, this trope is known as [[https://en.wikipedia.org/wiki/Contrafactum Contrafactum]]. Sometimes it's done to give a new song an air of familiarity; other times, as the beginning of this description suggests, it's simply done to allow a creator to use a PublicDomainSoundtrack rather than having to write or commission new music.

See also InTheStyleOf and SuspiciouslySimilarSong. SampledUp is when this version completely eclipses the original. {{Filk Song}}s are very frequently set to the tune of existing songs. Writing a song To The Tune Of an ''instrumental'' piece of music is so common that it has its own subtrope: WithLyrics.

When the point isn't that a new song was built out of an old one, but instead that the new song is a direct and overt ''parody'' of the old one, then the trope you're looking for is SongParody. (For all intents and purposes, To The Tune Of is the SuperTrope of Song Parody. Bear in mind, though, that quite a few excellent musical parodies don't actually recycle the music from the source material at all, relying instead on a SuspiciouslySimilarSong substitute.) Parodic examples of the practice should go on that page; non-parodic examples are found here.

While we're at it, please note that this has ''nothing'' to do with songs that happen to be in the same tempo. For instance, it's a well-known and curious fact that Music/{{LMFAO}}'s "Party Rock Anthem" matches the ''Franchise/StarWars'' Cantina theme [[http://www.youtube.com/watch?&v=84WpcmJ28Yg in the middle]], as well as [[TheRoaringTwenties the Charleston]] (as seen [[http://www.youtube.com/watch?v=fj9_PKu9UzE here]]). But this trope is about ''lyrics'', which the Cantina theme and the Charleston don't really have. As such, this fact is cute trivia, but has nothing to do with this trope. Besides, songs being in the same tempo is a "Administrivia/PeopleSitOnChairs" thing.

* The GoCompare jingle is to the tune of "Over There," by George M. Cohan of ''Film/YankeeDoodleDandy'' fame.

[[folder:Comic Books]]
* ''Magazine/MadMagazine'' ''thrived'' on this trope through TheSeventies, doing any number of musical parodies of popular properties (including ''StarTrek'' and ''StarWars''), whose musical numbers always included footnotes informing the reader of the appropriate tune.

[[folder:Fan Fic]]
* ''Fanfic/CalvinAndHobbesTheSeries''' theme takes ''[[UsefulNotes/{{Plagiarism}} a lot]]'' of inspiration from the ''WesternAnimation/{{SpongeBob|SquarePants}}'' theme (itself an example of this trope), though the very first part of it is taken from ''WesternAnimation/GarfieldAndFriends''.

* The song in ''Film/CitizenKane'' (you forgot there was a song in ''Citizen Kane''? Shame!) borrows the tune of "A Poco No", a song by the Mexican composer Pepe Guízar.
* In the 1988 comedy ''Film/MoonOverParador'', the new president changes the national anthem to "Parador, te amo" ("I love you, Parador"), which goes to the tune of "Bésame Mucho". Music/SammyDavisJr sings it.

* Parodied in ''Literature/HarryPotterAndThePhilosophersStone'', in which the Hogwarts song can be (and is) sung to ''any tune at all''.
* ''Take Me Out of the Bathtub and Other Silly Dilly Songs'' and its sequels take old classic children's songs and provide humorous lyrics to them, often relating to an average child's life
* Lampshaded in ''Literature/ThroughTheLookingGlass'', in which the White Knight promises a tune "of [his] own invention".

* ''Series/{{Community}}'':
** When Pierce tries to write a song for the college, he repeatedly does this with children's songs. It also turns out he did this with ads for Hawthorne Wipes. After a comment from Annie, he finally writes a school song...set to "The Way It Is" by Bruce Hornsby And The Range.
** "[[Recap/CommunityS1E12ComparativeReligion Comparative Religion]]" ends with the group performing an inclusive, secularized rewrite of "Silent Night". (''Sensible night, appropriate night / Snow on ground, left and right...'')
* "The Lumberjack Song" of ''Series/MontyPythonsFlyingCircus'' and the older ''Radio/TheGoonShow'' song "Ying Tong Song" both use very similar arrangements to Eddie Morton's [[http://www.youtube.com/watch?v=QbsXLDNPvNc "I'm a Member of the Midnight Crew"]], which was long out of print when the two shows came along. (You might recognize it from it being referenced in ''{{Webcomic/Homestuck}}''.)
* In ''Series/DoctorWho'', the Third Doctor sings a "Venusian lullaby" to a monster (specifically, the Monster of Peladon) that somehow has the same tune as "God Rest Ye Merry, Gentlemen."
* ''Series/SpittingImage'''s "We've Ruined the World" is an aversion. It's clearly meant to be sung to the tune of "What a Wonderful World", but presumably either the rights weren't available or the holders objected.
* The [[Series/BarneyAndFriends Barney franchise]] is known for adding new lyrics to traditional kids' songs, notably the theme song and the closing tune "I Love You," sung to "Yankee Doodle" and "This Old Man" respectively.
** Save for some exceptions (mostly the theme and "I Love You"), this is [[AvertedTrope averted]] in more recent Barney episodes and videos.
* ''Series/ElmosWorld'' is another offender, with it's theme tune that's sung to ''Jingle Bells''.
* Series/{{Bill Nye|TheScienceGuy}} also features one at the end of [[OnceAnEpisode every episode]] of the show. And they were surprisingly good.
* The opening theme to NBC's Sunday Night Football was, for several years, done to the tune of "I Hate Myself For Loving You" by Music/JoanJett. The current version, sung by Carrie Underwood, is a SuspiciouslySimilarSong.
* Rebecca from ''Series/{{Cheers}}'' hired a songwriter to compose a jingle for the bar only to discover his method was to do this with children's songs. She fires him, only to discover his previous jingle was rather effective.
* One task on ''[[Series/TheApprentice The Celebrity Apprentice]]'' was to make an ad for a Mexican-themed beverage. Ian Ziering repeatedly tried get his team to use his suggestion: a jingle to the tune of "La Cucaracha''. However, he was rejected just as repeatedly. After his team lost, he brought it up in the boardroom. Drumpf was so infuriated that he wanted to use a song he couldn't use, he fired Ziering immediately.
* ''Series/TheOfficeUS'': Michael learns the Pledge of Allegiance by singing it to "[=Old McDonald=]."

* "Anti-You" and "Burning Bridges" by Music/BlueStahli have the same music but entirely different lyrics.
* Music/TomLehrer did this twice:
** "The Elements" uses the tune of the "MajorGeneralSong" from ''Theatre/ThePiratesOfPenzance''.
** "The Hound Song", written for ''Series/TheElectricCompany1971'', uses "Caro nome" from ''Theatre/{{Rigoletto}}''.
* Music/WeirdAlYankovic set the words of "[[Series/TheBeverlyHillbillies The Ballad of Jed Clampett]]" to the tune of "Money for Nothing" by Music/DireStraits, [[http://www.youtube.com/watch?v=P4SDhrTPOiI like so]].
* Similarly, Pinkard and Bowden set the words of the ''Series/GreenAcres'' theme song to the tune of "[[Music/JimiHendrix Purple Haze]]".
* "La vallee de Dana" is a French song that topped the charts in the 90's, about a battle between Gauls and Cimmerians, to the tune of "Tri Martolod". The original is a folk song about three sailors.
* Scooter's "How much is the fish?" uses an old French song about cider (Son ar Chistr) as its {{Leitmotif}}.
* In a case legally ruled to be plagiarism, "Hail! Hail! The Gang's All Here" appropriated the tune of "With Catlike Tread" from ''Theatre/ThePiratesOfPenzance''.
** The tune itself, though technically an original melody, is [[SuspiciouslySimilarSong a reference to]] "The Anvil Chorus" from ''Il Trovatore'' by Music/GiuseppeVerdi. Listen to the "Come, friends who plough the sea" bit.
* Music/GeorgeHarrison's ''My Sweet Lord'' from ''Music/AllThingsMustPass'' was ruled to have plagiarized the melody of The Chiffons' ''He's So Fine'', in a case of what the judge called "unconscious copying". Harrison later bought the rights to the song to avoid further legal entanglements.
* "Twinkle twinkle, little star..." / "A B C D E F G..." And they're all based on the French song "Ah vous dirai-je, Maman" -- which itself inspired a [[http://en.wikipedia.org/wiki/File:12_Variations_Tema.ogg 13-part]] [[http://en.wikipedia.org/wiki/File:Variation_I.ogg Mozart piece]].
** Germans know this one as "Morgen kommt der Weihnachtsmann" ("Tomorrow comes Santa" -- a Christmas song!)
** In Hungary it's known as "Hull a pelyhes fehér hó" ("Fluffy white snow is falling") -- Another Santa-themed song (maybe a translation of the German one?).
** Finnish children learn both the ABC song and the star song (called "Tuiki tuiki tähtönen"). There was a third song to the same tune, "Lapsukaisten koululaulu" (starting with "koska meitä käsketään"). It's been pretty much forgotten about, probably because it's basically propaganda of 50's values.
** ''Twinkle twinkle, Little Star'' not only shares its tune with ''The Alphabet song'', but also sounds suspiciously close to ''Baa baa, Black Sheep'', and to a lesser extent, ''I Have a Little Nut Tree''.
* Music/{{Coldplay}} [[http://www.youtube.com/watch?v=8Z2x8q5wMfk have been accused of doing this]] with their song "Viva la Vida" (which, itself, is about a king), being accused of copying the melody from four different sources: alternative rock band Creaky Boards (who retracted the claim and decided that both bands probably stole the tune from VideoGame/TheLegendOfZelda), guitar virtuoso Music/JoeSatriani's "If I Could Fly," and Cat Stevens' "Foreigner" suite. And "Talk" borrows ITS main riff and parts of ITS melody from Music/{{Kraftwerk}}'s "Computer Love" -- though they sought permission before releasing it, and the members of Kraftwerk are credited with co-writing the song.
** On the topic of "Viva la Vida", there's more than that, actually. The above three are the most well known because they were the only 3 to accuse Coldplay of plagiarism. There's actually more things that sound similar to Viva la Vida, like Francis Limon, Ding Dong Song, J'en Ai Marre, Hearts, and Dirty Diaper Blues. Or at least that's what [[http://www.youtube.com/watch?v=fxSIAXGakuk&feature=related this video]] is saying. And there may be more. And there may be similar sounding songs made ''after'' Viva la Vida. Someone should make a medley based on that single melody and its variations.
** Music/MitchBenn wrote a song, referencing his earlier "Everything Sounds Like Coldplay Now" about new bands copying Coldplay's style, called "[[http://www.youtube.com/watch?v=n2pdv6faw8M Now Coldplay Sound Like Everything Else]]" (to the tune of 'Viva la Vida'.)
* As pointed out in ''Film/MrHollandsOpus'', "A Lover's Concerto" by The Toys uses the sweet strains of Christian Petzold's "Minuet in G" stretched to four-quarter time.
* A huge number of Music/ElvisPresley's hits were new lyrics written for old music. "It's Now or Never" is a cover of the 1898 Neapolitan aria "O sole mio". "Can't Help Falling in Love" uses a melody from 1780. "Love Me Tender" is a version of "Aura Lee", written in 1861. "There's No Tomorrow" is another.
* "Danny Boy" is only one of many lyrics set to the tune of "Londonderry Air" (though "Danny Boy" originally had a different tune, believe it or not). Just try to explain the "simple" progression here: The theme to the anime ''Anime/RomeoXJuliet'' is "Inori~You Raise Me Up〜" sung by Lena Park. That was a take-off of "You Raise Me Up" by Rolf Løvland of Secret Garden. This was taken from "Danny Boy", which is, in turn, set to the tune of "Londonderry Air".
* Music/BrightEyes' "Road To Joy", as the title hints, takes ITS melody from Beethoven's "Ode To Joy".
* A related phenomenon: Jazz compositions often consist of new melodies laid over the chord changes of some standard. "Hot House" (based on Music/ColePorter's "What Is This Thing Called Love?") may be the most famous example.
* Music/EdwardElgar's ''Pomp and Circumstance March No. 1'', composed in 1901, was almost immediately given words to turn it into the patriotic hymn ''Land of Hope and Glory'' for King Edward [=VII=]'s coronation in 1902. In the [=US=], it is still often performed without the lyric, most often at school graduations.
* "My Way," most famously performed by Music/FrankSinatra from ''Music/MyWay'', is set to the tune of a French song, "Comme d'habitude" by Claude François.
* Music/MichaelJackson was accused of doing this with "Will You Be There" from ''Music/{{Dangerous}}'', apparently set to the tune of a song by Italian singer Al Bano. Italian courts eventually ruled in favor of Jackson. Bano had to pay Jackson's legal fees. The song does start with a snippet of Music/LudwigVanBeethoven's 9th Symphony, however (and this Jackson also got in trouble for as initial releases lacked the proper credit; this was promptly fixed.)
* "This Land Is Your Land", by Music/WoodyGuthrie is from the traditional folk song "Oh, My Loving Brother"
* The Music/RedHotChiliPeppers were accused of ripping off Tom Petty's "Mary Jane's Last Dance" with their own "Dani California".
* Music/{{Nirvana}} were accused of copying the bass riff from "Eighties" by Music/KillingJoke for their song "Come as You Are".
** Kurt Cobain admitted that with "Smells Like Teen Spirit" he was trying to write a Music/ThePixies}} song, and the end result sounds quite a bit like their song "U-Mass" in terms of overall sound and "Debaser" in terms of the main riff. And then when the song came out non-alt rock people thought it sounded like "More Than a Feeling", which he was also aware of:
-->"It was such a clichéd riff. It was so close to a Boston riff of 'Louie Louie'."
* "Alouette" = "Down By the Station" = "The Itsy Bitsy Spider"
* "I Fear IKEA" by The Lancashire Hotpots is sung to the tune of "The Wild Rover". ("That's why I fear IKEA (clap-clap-clap-clap) I won't go there again! I don't want a bookcase called Billy, or a table called Sven!")
** Others include "Bitter Lager Cider Ale Stout" (to the tune of "She'll Be Coming Round the Mountain") and "Dolby 5.1" (to SuspiciouslySimilarSong of "Matchstalk Men and Matchstalk Cats and Dogs").
** Actually most Hotpots songs. Some aren't quite so obvious to people without a folk music background, though.
** On another note, when hearing ''The Wild Rover'''s chorus for the first time, most Germans start singing ''An der Nordseeküste'' (At the north sea's coast), a silly song by silly East Frisian singers ''Klaus & Klaus''.
* Music/PetShopBoys' "It's a Sin" was alleged by the 80s DJ Jonathan King to have plagiarized Cat Stevens' "Wild World" and remixed Stevens' vocals to the PSB version onto a single (see the George Harrison case above; it was the B-Side to this single). The funny thing is that Stevens' version actually sounds a lot more like "It's a Sin" than King's version.
* Music/TheKinks' "Catch Me Now I'm Falling" has a guitar riff similar to Music/TheRollingStones' "Jumpin' Jack Flash", while the ending of "U.K. Jive" recalls Music/TheWho's [[Music/MyGeneration "My Generation"]].
** Music/TheWho's "I Can't Explain" has a similar feel and guitar tone to Music/TheKinks' "You Really Got Me". Both were produced by Shel Talmy, and Townshend himself admitted "Explain" was written as a Kinks ripoff. Music/TheClash later used the riff from "I Can't Explain" twice, once for "Clash City Rockers" and again for "Guns On The Roof".
** As does Music/TheDoors' "Hello, I Love You" from ''Music/WaitingorTheSun'' to "All Day and All of the Night."
* Music/BruceSpringsteen's "Outlaw Pete" has a similar melody to Music/{{Kiss}}' disco single, "I Was Made For Lovin' You" from ''Music/{{Dynasty}}''.
** The Boss is a phenomenal songwriter otherwise, but [[http://www.youtube.com/watch?v=MtrOYsNCPmg Radio Nowhere]] is essentially [[http://www.youtube.com/watch?v=tBHJqtgo8RA 867-5309]] made heavier and more awesome.
* Mägo de Oz, a Spanish PowerMetal[=/=]FolkMetal band, is very prone to this. As an example, they have a song, "En Nombre De Dios", which is basically "The Gates of Babylon" by Rainbow + new lyrics about the CorruptChurch.
* Music/{{Radiohead}}'s "Karma Police" from ''Music/OKComputer'' uses piano passages that are lifted almost verbatim from the Beatles' "Sexy Sadie" from ''Music/TheWhiteAlbum''.
* Music/EricCarmen's hit song "Never Gonna Fall in Love Again" is essentially the 3rd movement of [[Music/SergeiRachmaninoff Rachmaninoff]]'s 2nd Symphony.
* Music/{{Cherry}}'s "Yes I Will" uses the tune of Music/{{Pink}}'s "U & Ur Hand" verbatim.
* When Music/BillyJoel wrote "Uptown Girl", he in part (accidentally) plagiarised a Mozart piece.
* Music/{{Metallica}}'s "The Unforgiven II" sounds almost exactly like "Children of the Damned" by Music/IronMaiden (which itself resembles "Simple Man by Music/LynyrdSkynyrd).
* Music/ChuckBerry may have spawned a lot of (textual) copyings, starting with the tune ''Too much monkey business'', which led to Music/BobDylan`s "Subterranean Home Sick Blues" from ''Music/BringingItAllBackHome'', which eventually inspired Music/{{REM}} to make ''It`s the end of the world as we know it (and I feel fine)'' from ''Music/{{Document}}''. Music/BillyJoel also joined in, with ''We didn`t start the fire'', almost certainly ripped from Dylan.
* "Si pido otra cerveza" by Los Inhumanos uses the tune of "Oh! Susanna" by Stephen Foster.
* Solarstone's "[[https://www.youtube.com/watch?v=vE80EivmL04 Part of Me]]" is based on the tune of the Celtic standard "[[https://www.youtube.com/watch?v=zZAlG0xokS4 "She Moved Through The Fair]]".
* Music/{{Les Luthiers}} have fun with this trope: in one of their shows, the narrator mentions Johann Sebastian Mastropiero always used the same music for all his operas. He describes a scene from one, but then they perform a scene from another opera ("La Hija de Escipión").
* The Brian Setzer Orchestra's [[https://www.youtube.com/watch?v=t8jsyBsIwgY "Yabba Dabba Yuletide"]] has original Christmas-themed lyrics to the tune of the theme from ''WesternAnimation/TheFlintstones''.
* ''The Twelfth of Never'', a song that's made popular by Johnny Mathis, lifted its tune wholesale from the folk song ''The Riddle Song, aka I Gave My Love A Cherry''
* Bryant Oden gives us [[https://www.youtube.com/watch?v=C-V6FHWYtcg The Long Word Song (Hippopotomonstrosesquipedaliophobia)]] based around [[Film/MaryPoppins Supercalifragalisticepialidocious]]. [[JustifiedTrope Completely justified]] seeing as the song centers around long words (though the Mary Poppins word itself is sadly not mentioned).
* "The Eyes of Texas" is to the tune of "I've Been Working On the Railroad", while "Maryland, My Maryland" uses "O Christmas Tree".
* Folk song "Banks of the Sacramento" is roughly to the tune of "Camptown Races".
* Anti-Communist folk singer Janet Greene did this a couple of times - "Commie Lies is set to the tune of "Blue-tail Fly" (aka "Jimmy Crack Corn"), while "Comrade's Lament" is set to Gilbert and Sullivan's "Policeman's Song" from ThePiratesOfPenzance.
* [[http://ultimateclassicrock.com/h-p-lovecraft-nemesis-piano-man/ Here we have the poem “Nemesis” by H. P. Lovecraft set to the tune of the song “Piano Man” by Billy Joel.]]


[[folder: Radio]]
* The ''Radio/ImSorryIHaventAClue'' round "One Song to the Tune of Another", in which panellists must [[ExactlyWhatItSaysOnTheTin sing one song to the tune of another]].[[note]]If that isn't clear, you could try thinking of a song as being a trope page and the words as being an example. If an example falls under more than one trope you can copy if off the first page (or "one song") and paste it into the second page (or "the tune of another"). [[{{Metaphorgotten}} You need to be careful it really does fit under both tropes though]], otherwise you might be better cut-and-pasting rather than copy-and-pasting. Why use paste at all? Because otherwise you might forget what the example was when you come to type it in. And the last thing anyone wants is to be staring blankly at a keyboard with no idea what they're supposed to do with it. At the piano, we have Colin Sell.[[/note]]

* The Catholic Mass (particularly the Latin version) is prone to a direct inversion this trope: it's a standard text that can be, and has been, set over and over again by different composers for different occasions.
** Not only that, but chunks of the Mass are often broken off and set as standalone pieces for choirs to sing; any choral piece called "Sanctus" or "Gloria" or "Agnus Dei" or "Kyrie"—and there are ''hundreds''—is likely to be a Mass excerpt sung To The Tune Of new music.
** And not only ''that'', but the Roman Catholic Liturgy often does this trope to ''itself''. "The Mystery of Faith" and "The Great Amen" are generally sung to the same tune (assuming, of course, that they are sung).
* Renaissance composers such as Josquin, Ockeghem and Dufay who created the foundations of our musical language worked almost ''exclusively'' with melodies that were not their own. Many of their settings of the Catholic Mass were even called "parody Masses", in the sense that they used short pieces of music (not just a melody) composed by others as a starting point. (Parody does not imply a humorous appropriation in this case.)
* All over the place in just about any hymnal:
** The hymns "For the Beauty of the Earth" and "As with Gladness Men of Old" both use "Dix", a melody composed by Conrad Kocher.
** "What Child Is This," a Christmas song, was written with the melody from "Greensleeves", an English folk song.
** Likewise, the hymn "Lord of the Dance" copied "Simple Gifts", a Quaker song.
** The traditional Gaelic hymn tune "Bunessan" has been used for the Christmas carol "Child in a Manger" and more commonly for the hymn "Morning Has Broken".
** "Battle Hymn of the Republic" comes from "John Brown's Body", as does "Oil Thigh," the FootballFightSong of Queen's University.
*** "John Brown's Body" was itself sung to an even earlier tune, "Say, Brothers, Will You Meet Us."
*** In turn, the union hymn "Solidarity Forever" used the same tune.
** Overall, it's a common practice for even new lyricists to repurpose existing familiar tunes for new hymns. This is why many hymnals include an index of tune names and meters in the back, so that accompanists and congregations can mix-and-match new words to familiar tunes or vice-versa. It's also ridiculously common to open two different hymnals and find them using totally different melodies for the same words. (For instance, the ''United Methodist Hymnal'' has a hymn titled "Forward Through the Ages" which uses the melody for "Onward, Christian Soldiers.")
** When the (Liverpool) Spinners performed the folk song "Old Johnny Booker" they got one woman complaining that the song was "sacrilegious" because it has the same tune as her favourite hymn. What she didn't realise is that both the hymn and the folk song lifted the tune from an earlier song.
** The tune "Winchester Old"; best known as the UK tune for "While Shepherds Watched Their Flocks by Night", but also the tune of several other hymns (and ''nearly'' the same as "There Is A Green Hill Far Away").
* The [[{{UsefulNotes/Mormonism}} Mormon]] children's ListSong "Books of the New Testament" is to the tune of the hymn "Praise to the Man", which itself is to the tune of "Scotland the Brave". Similarly, the song "Books of the Old Testament" is to the tune of the hymn "Do What is Right".

* Just about every [[UsefulNotes/AustralianRulesFootball Australian Football League]] club theme song is an existing song with rewritten lyrics, as can be seen [[http://www.youtube.com/watch?v=iSANBgZzi6o&feature=related here]]. The only exceptions are Fremantle (which includes a small section from "Song of the Volga Boatmen"), Port Adelaide and West Coast. * The [[http://www.youtube.com/watch?v=gbqQLsPCAhQ Perth Wildcats' anthem]] is to the tune of the "Hallelujah Chorus".
* American sports feature several examples of this trope...
** "Stand Up and Cheer", originally written for the University of Kansas in 1909 and now the school's secondary fight song, is now the primary fight song for 10 other colleges, five of them in NCAA Division I, and a secondary fight song for a second D-I school. And that's not getting into the ''hundreds'' of high schools that use the song.
** The "Washington and Lee Swing", written for and still in use by the small Virginia university of that name, is also used by hundreds of high schools.
** One of LSU's secondary fight songs, "Hey, Fightin' Tigers", is the Broadway tune "Hey, Look Me Over"[[note]]from the musical ''Wildcat''[[/note]] with new lyrics.
** Another Broadway tune, "Step to the Rear",[[note]]from ''How Now, Dow Jones''[[/note]] became South Carolina's current fight song, "The Fighting Gamecocks Lead the Way".
** And to link US college sports with the Australian Football League, the Sydney Swans' fight song is Notre Dame's "Victory March" with new lyrics.

* Entire genres of theatre work under this principle. For instance, "ballad operas" -- the most famous probably being John Gay's ''Theatre/TheBeggarsOpera'' -- took popular tunes and rewrote their lyrics to tell a story. (Note, though, that Weill and Brecht's adaptation of ''The Beggar's Opera'', ''Theatre/TheThreepennyOpera'', had original music, except for the "Morning Anthem", which reused one of the 18th-century tunes.) The genres of "burlesque", "extravaganza" and a few others were the same. Most of these genres are completely or near-completely dead, except for British {{pantomime}}s (a sort of very silly Christmas show, with crossdressing and audience participation), which appear every year in Britain.
* Almost all of Händel's operas, cantatas and oratorios borrowed music from himself or even adapted from other composers, in varying amounts.
* The famous "Habanera" from Bizet's ''Theatre/{{Carmen}}'' was based on what the composer originally thought to be a folk melody, but turned out to be a composition of a contemporary Spanish musician Sebastian Iradier called "El Arreglito". Bizet acknowledged this in the score.
* ''Theatre/TheCocoanuts'' has a comic number with the NonAppearingTitle "The Tale of a Shirt" which consists of new lyrics written to the Habañera and Toreador Song from ''Theatre/{{Carmen}}''.
* Musicals by Creator/AndrewLloydWebber frequently use the same tune multiple times for different lyrics.
** ''Theatre/AspectsOfLove'' is particularly prone to this, with the melody of "Love Changes Everything" used for pretty much any circumstance at all. The critic for ''The Independent'' commented:
-->As the evening goes on, ''Aspects of Love'' increasingly resembles one of those snow-scene knick-knacks with a built-in music box: every few minutes, it's shaken furiously and the scenery rearranges itself, but, after the dust settles, the same tune re-emerges. … Would the young Lloyd Webber [watching ''Theatre/SouthPacific'' as a child] have been as impressed by "Some Enchanted Evening" if it had popped up 10 minutes later as "Would You Like A Biscuit?"?
* In ''Theatre/ThePiratesOfPenzance'', the Major-General enters to a tune we've heard before: the Pirate King's IAmSong.
** Lampshaded in the Creator/KevinKline film version.
-->'''Pirate King''' (''in an angry aside to one of the pirates''): That's the same as the Pirate King tune!
* Inverted by the songs in Creator/WilliamShakespeare's plays, which often get set to completely new tunes for new productions.
* Broadway songwriters Robert Wright and George Forrest milked this trope for all it was worth: their hit musicals ''Theatre/{{Kismet}}'' and ''Song of Norway'' were cobbled together out of melodies by Alexander Borodin and Edvard Grieg, respectively. Other shows of theirs reworked tunes by Victor Herbert, Heitor Villa-Lobos, Johann Strauss, and Sergei Rachmaninoff.
* In ''Theatre/TheMagicFlute'', the melody sung by the two ThresholdGuardians is that of Martin Luther's "Ach Gott, vom Himmel sieh' darein." Its arrangement is a stylistic homage to Music/JohannSebastianBach's chorale preludes.

* The many, many, ''many'' remixes of ''{{VideoGame/Touhou}}'' music occasionally uses other tunes from Music/WolfgangAmadeusMozart to Music/IronMaiden.
* In ''VideoGame/MassEffect2'', a dialog path leads to eccentric scientist Mordin Solus singing "Scientist Salarian" to the tune of the MajorGeneralSong from ''Theatre/ThePiratesOfPenzance''
* ''{{VideoGame/Dishonored}}'' has "Drunken Whaler," which follows the tune and basic premise of the well-known real-life sea shanty ''[[https://en.wikipedia.org/wiki/Drunken_Sailor Drunken Sailor]]''--threatening new sailors with severe punishment should they be caught drunk or hung over before their shift. This version, however, replaces the original's mix of cruel pranks, impractical hangover cures, and severe (but not permanently damaging) corporal punishments with torturous, cold-blooded murder. And considering the [[CrapsackWorld Crapsack]] setting and dirge-like reverence with which it's sung, it's heavily implied these threats are deadly serious.

* The song sung by the Easter Bunny in ''Webcomic/SluggyFreelance'' is not-so-subtly modified from the Lumberjack song from ''Series/MontyPythonsFlyingCircus''. Which in turn is based on one of Music/WolfgangAmadeusMozart's operatic arias.
* In Webcomic/TheOrderOfTheStick [[http://www.giantitp.com/comics/oots0445.html #445]] (warning, spoilers!), Elan sings a song which is told in a note that it's sung to the tune of "O Danny Boy".

[[folder:Western Animation]]
* ''WesternAnimation/{{Animaniacs}}'' and its spin-off ''WesternAnimation/PinkyAndTheBrain'' often feature songs set to the tune of already-existing public domain songs, but with original lyrics.
** The song "[[https://www.youtube.com/watch?v=h5f56Ynb01E Brainstem]]" is set to the tune to "[[https://www.youtube.com/watch?v=noYptXPHiAE Camptown Races]]".
** The song "Here Comes Attila" was a song abour UsefulNotes/AttilaTheHun sung to the tune of "Get Out the Way, Old Dan Tucker".
* In-universe example with WesternAnimation/{{Arthur}}: [[ShowWithinAShow Mary Moo-Cow]]'s theme song is sung to ''Frere Jacques''.
** Real-Life example: The Actimates D.W. sang a birthday song to the tune of ''London Bridge'' on your birthday.
* While WesternAnimation/TheBackyardigans usually have original music, the song ''What Do You Do With A Scurvy Pirate?'' is a filk of the shanty classic ''[[https://en.wikipedia.org/wiki/Drunken_Sailor Drunken Sailor]]''.
* ''WesternAnimation/CampLazlo'': The "Buddy Wuddy" song from ''Parasitic Pal'' was modified, complete with the same singers, for the same-titled song from ''Loogie Llama''.
** The TitleThemeTune is done to the tune of "B-I-N-G-O".
* ''WesternAnimation/FamilyGuy'' did this several times. The tune for "The FCC Song" is from ''Take Me Along'', an old Broadway musical. The tune for "A Bag of Weed" is "Me Ol' Bamboo" from ''Chitty Chitty Bang Bang.'' Whether a given song from the show counts as this trope or straight-up parody mostly depends on [[WeirdAlEffect how obscure the originals were]].
* One of the cases on ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' consisted of him prosecuting for a Japanese band called Shoyu Weenie[[note]]Soy sauce sausages[[/note]], who were accusing the Neptunes (yes, from ''WesternAnimation/{{Jabberjaw}}'') of stealing their hit.
* WesternAnimation/LooneyTunes famously used opera tunes for ''WesternAnimation/RabbitOfSeville'' and ''WesternAnimation/WhatsOperaDoc''.
* ''WesternAnimation/TheSimpsons'' -- "O Whacking Day" is strong LyricalDissonance for Americans and Germans familiar with the yuletide hymn "O Christmas Tree"/"O Tannenbaum", less so for Britons who know the bloodthirsty lyrics of the revolutionary hymn of the same tune, "The Red Flag" (to give you a taste, the first two lines are "The People's flag is deepest red/it shrouded oft our martyred dead").
** The climax of "Wild Barts Can't Be Broken" involves the children and adults of Springfield performing a CounterpointDuet to the tune of "Kids" from ''Theatre/ByeByeBirdie''.
** In "The Boys of Bummer", Jimbo, Dolph, and Kearney sing [[Music/TheJGeilsBand "Bart Stinks"]] when Bart becomes a townwide pariah.
-->'''Bart:''' Aww, my favorite song ruined!
* The ''WesternAnimation/TotallySpies'' ThemeTune uses the tune of the rather obscure song "Here We Go" by Moonbaby.
* "Blow The Man Down" and the opening theme to ''WesternAnimation/SpongeBobSquarePants''.
* One of the ending tunes of CampCandy is sung to the tune of ''On Top of Ol' Smokey''
* WesternAnimation/GarfieldAndFriends had Binky The Clown's [[HappyBirthdayToYou birthday song]] sung to "Freres Jacques".
** One episode of ''WesternAnimation/JusticeLeague'' had a commercial jingle playing on the Batmobile's radio that used that tune.
* The short lived cartoon ''Pro Stars'' originally had a theme song with new lyrics set to Music/{{Queen}}'s "We Will Rock You". This was rather appropriate given that the song is a staple of sporting events and the main characters were fictionalized versions of famous athletes (Michael Jordan, Wayne Gretzky, and Bo Jackson). Unfortunately, Queen frontman Freddie Mercury died from AIDS a couple of months into the show's run and a new theme song was put in place.
* ''WesternAnimation/JuliusJr'' also uses ''What Do You Do With A Drunken Sailor'' with original lyrics in ''Perfect Pirate Day''. They then sang a song with original lyrics about staying awake to the tune of ''Brahms Lullaby'' in ''Smellalicious Flower''
