History AwesomeMusic / Omori

Let's put it this way: ''Omori'''s soundtrack is so incredible that, much like ''Undertale'', ''Final Fantasy'', and ''The Legend of Zelda'', it got its own [[https://youtu.be/OG6HJRpqs_8?si=FPjRHsN8L0TRRv53 orchestral performance]].

* The basic version of [[https://youtu.be/hLDull8aPDw?si=Q3-pRLHUNxc9IqU4 "Lost At A Sleepover"]] is a short but sweet piece that emphasizes childlike wonder. The version that was played [[https://youtu.be/jk1najdr5-8?si=p_2JHEFH-Z-8XAd0 at the third anniversary concert]], however, is downright gorgeous, with added measures of music and a more natural sound that really gives the song an added little something.

* [[https://www.youtube.com/watch?v=8wKWwUzgCE8 "It Means Everything."]] When all your pent up anger and sadness reaches a boiling point, and your ex-friend confronts you in your one safe place, and you can't hold back the violent impulses anymore. [[https://youtu.be/VllDfvw7jPM?si=BOip2q-aMKd3ANXU The 3rd anniversary concert version]] is played with "Just Leave Me Alone" and "Cram It, Wad", giving the entire song an even more angry feel to it that's befitting of the buildup.

* [[https://www.youtube.com/watch?v=rlQd9qWKjLM "World's End Valentine"]], an intense theme that plays during the battle against Sweetheart and is about as obnoxiously manic as Sweetheart herself. Certainly takes the sting out of how difficult the fight is. [[https://youtu.be/nuSzUXfuIv0?si=-hHXsyjkTdmm1PTA The 3rd anniversary concert version]] has all the excellent parts of the original, albeit now with a few amazing solos mixed into it.

* [[https://www.youtube.com/watch?v=W766EABGHe8 "OMORI"]], the FinalBoss theme. ''Perfect'' SadBattleMusic. If OMOCAT wanted to portray the tragedy of [[HopelessBossFight fighting a losing battle against the personification of your suicidal ideation]] through music, then OMORI succeeds with flying colors. [[https://youtu.be/XfeLiBT3Ejs?si=MO8MRDjtYL_FRlg- The 3rd anniversary concert version]] has an even ''more'' emotional violin leading the piece, and the massive amount of supporting strings give it a truly epic feel. It also flawlessly transitions into the below-mentioned "ALTER".

* [[https://www.youtube.com/watch?v=ACon4txJiDA "DUET"]], the title theme's TriumphantReprise, plays after Sunny defeats Omori and can play the recital with Mari that never got to happen in real life, and is a beautiful violin and piano duet that is equal parts heart-warming and tragic for what it represents. For the characters and the player, this piece is catharsis and closure all rolled into one. [[https://youtu.be/f0XU_4vXRhc?si=YuubOkDvIeqzZRjs The 3rd anniversary concert version]] is everything that the original was, albeit with the added benefit of truly sounding like it was being played in a recital hall. Basically, the concert version is what their duet would have truly sounded like in-person.

* [[https://www.youtube.com/watch?v=8wKWwUzgCE8 "It Means Everything."]] When all your pent up anger and sadness reaches a boiling point, and your ex-friend confronts you in your one safe place, and you can't hold back the violent impulses anymore.

If OMOCAT wanted to portray the tragedy of [[HopelessBossFight fighting a losing battle against the personification of your suicidal ideation]] through music, then OMORI succeeds with flying colors.
* [[https://www.youtube.com/watch?v=bKC8qqqLZ6A "OMORI - ALTER"]], an alteration of "OMORI". It suddenly kicks in without warning the first time Omori inflicts the Afraid status on you. It features "OMORI" in the background being drowned out by chaotic noise as Sunny desperately but hopelessly tries to hold onto himself while Omori gets stronger and stronger.

* [[https://www.youtube.com/watch?v=ACon4txJiDA "DUET"]], the title theme's TriumphantReprise, plays after Sunny defeats Omori and can play the recital with Mari that never got to happen in real life, and is a beautiful violin and piano duet that is equal parts heart-warming and tragic for what it represents. For the characters and the player, this piece is catharsis and closure all rolled into one.

* [[https://www.youtube.com/watch?v=zDAPRmM1GN8 "Battle Among Friends"]] is a playful chaotic mixture of several previous tracks, between "Splintered Sweets in the Castle", "Tussle Among Trees", and even "My Time". It even uses ''airhorns'' to good effect! Although it's one of the trickiest fights in the game, it feels more like a silly play-fight among friends.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/omori_3rd_anniversary_concert_key_art.png]]

* [[https://youtu.be/RkQ1cgvkylI "Three Bar Logos"]] is an amazing battle theme to follow up Tussle Among Trees. It sets up the wacky and fun vibe of Otherworld perfectly with a fast-paced beat as you smash floating oranges out of the sky.

* [[https://youtu.be/RkQ1cgvkylI "Three Bar Logos"]] is a perfect battle theme to follow up Tussle Among Trees. It sets up the wacky and fun vibe of Otherworld perfectly with a quick and cool beat.

With a soundtrack of over 179 tracks composed by such artists as Pedro Silva, Jami Lynne, and Music/BoEn, the soundtrack of ''Omori'' is one of the best in any indie game.

* [[https://www.youtube.com/watch?v=DWxiVN9eWVY "Tussle Among Trees"]] is an adorable track that nicely kicks of the simplistic encounters of [[GreenHillZone the Vast Forest]].

* [[https://www.youtube.com/watch?v=Pe---DN2TmY "You Cannot Go Back"]], which plays against Space Ex-Husband in the Hikkikomori route, is a more sinister remix of "You Were Wong. Go Back", complete with a DarkReprise of his mixtape.

* [[https://www.youtube.com/watch?v=7GIWV__qx4M "By Your Side."]] is Mari's {{Leitmotif}}, and is always a calm, welcoming piano piece to hear, befitting the safety of a healing and save point. Its simplicity leaves it open to reprises like [[https://www.youtube.com/watch?v=t3b52Z2qtfw "Dear Little Brother..."]] for some of the more emotional moments of the game.

* [[https://www.youtube.com/watch?v=MQYmjpdA_Pw "See You Tomorrow"]] is a relaxing and nostalgic acoustic guitar piece that plays during in Faraway Town in the evening, signifying the end of a long day and some peace after any troubles that may have occurred earlier. A more somber reprise on piano, [[https://www.youtube.com/watch?v=5s-1dej9Gsc "Crossroads"]], plays as Sunny awakens in Memory Lane and starts on the path to accept the truth.

* Something's three themes share the same simple melody, but combine it with various sound effects to turn them into the musical form of the phobias they represent. [[https://www.youtube.com/watch?v=wMfwS3xsH0s "Acrophobia"]] has repeated sliding tones punctuated with abrupt cuts to give the feeling of falling and impacting the ground, [[https://www.youtube.com/watch?v=ASrtjconCdc "Arachnophobia"]] keeps a low crackling sound to represent the chittering of bugs, and [[https://www.youtube.com/watch?v=lB7Lxd_1TYQ "Thalassophobia"]] muffles itself with swirling sounds to replicate the feeling of being submerged without a way out.

* [[https://www.youtube.com/watch?v=aFwkKTITYKA "Sweet Paralysis"]], perhaps a pun on Sleep Paralysis, is creepy and tense theme that plays against the two Kings: Crawler and [[OptionalBoss Carnivore]].

* [[https://omori.bandcamp.com/track/bready-steady-go BREADY STEADY GO]], the Unbread Twins' intense battle theme, perfectly matches their profession.

* [[https://www.youtube.com/watch?v=zDAPRmM1GN8 "Battle Among Friends"]] is a playful chaotic mixture of several previous tracks, between "[[https://omori.bandcamp.com/track/splintered-sweets-in-the-castle Splintered Sweets in the Castle]]", "[[https://omori.bandcamp.com/track/tussle-among-trees Tussle Among Trees]]", and even "My Time". It even uses ''airhorns'' to good effect! Although it's one of the trickiest fights in the game, it feels more like a silly play-fight among friends.

* [[https://omori.bandcamp.com/track/your-catastrophes-procession Your Catastrophes - Procession]], the theme for the second phase of the Basil fight. The haunting bells in the piece take an already spooky theme and dials it up to 11, making this theme feel right at home in a ''VideoGame/{{Castlevania}}'' game. Fitting as Sunny suffers a [[FreakOut nervous breakdown]] and brutally fights back against Basil.
* [[https://omori.bandcamp.com/track/omori OMORI]], the FinalBoss theme, is perfect SadBattleMusic. If OMOCAT wanted to portray the tragedy of [[HopelessBossFight fighting a losing battle against the personification of your suicidal ideation]] through music, then OMORI succeeds with flying colors.
* [[https://omori.bandcamp.com/track/omori-alter OMORI - ALTER]], an alteration of "OMORI". It suddenly kicks in without warning the first time Omori inflicts the Afraid status on you. It features "OMORI" in the background being drowned out by chaotic noise as Sunny desperately but hopelessly tries to hold onto himself while Omori gets stronger and stronger.
* Music/BoEn's "[[https://omori.bandcamp.com/track/my-time My Time]]" from the trailer progressively descends into hell. It also plays during the [[https://www.youtube.com/watch?v=0Fql2lbaTlo bad ending]] where Sunny/Omori commits suicide.
* The title theme gets a TriumphantReprise in [[https://omori.bandcamp.com/track/duet DUET]], which plays after Sunny defeats Omori and can play the recital with Mari that never got to happen in real life, and is a beautiful violin and piano duet that is equal parts heart-warming and tragic for what it represents. For the characters and the player, this piece is catharsis and closure all rolled into one.
* [[https://omori.bandcamp.com/track/clean-slate Clean Slate]] plays after Sunny awakens in the hospital after defeating Omori. Its ethereal-sounding tones greatly convey the feeling of the dust settling after the story's climax, and that Sunny's ready to start over on a clean slate at the end of this journey.
* [[https://omori.bandcamp.com/track/good-morning Good Morning]], the credits theme for the Good Ending, is a wonderfully calming track that emphasizes that for Sunny, it's time to make a fresh start in life.

* [[https://omori.bandcamp.com/track/title-2 The title theme]] is a simple piano piece and the first thing you hear when you start up the game. For the first track ever, it easily establishes that ''Omori'' will be an emotional game.

* "[[https://www.youtube.com/watch?v=wtVHR_1fS5k WHITE SPACE]]", the first theme heard in the game, is only three notes, yet seems to carry a weight of both comfort and sinisterness to it. It gets one ''hell'' of a DarkReprise in "[[https://www.youtube.com/watch?v=gAWLivIzTKc Welcome Again.]]", which swaps out the electronic-sounding notes for horrific, unsettling bells. Guaranteed to put you on edge whenever you return to the hub of BLACK SPACE.
* [[https://omori.bandcamp.com/track/by-your-side By Your Side.]] is Mari's {{Leitmotif}}, and is always a calm, welcoming piano piece to hear, befitting the safety of a healing and save point. Its simplicity leaves it open to reprises like [[https://omori.bandcamp.com/track/dear-little-brother Dear Little Brother...]] for some of the more emotional moments of the game.

* [[https://omori.bandcamp.com/track/finding-shapes-in-the-clouds Finding Shapes In The Clouds]] has to be one of the most joyful, happy, playful sounding 'field' themes ever heard in a JRPG. But then, if one thinks about it, this is the first time in four years Sunny stepped out of his house and had an actual friend to hang out with, and this song is likely what is going on in his mind.
* [[https://omori.bandcamp.com/track/see-you-tomorrow See You Tomorrow]] is a relaxing and nostalgic acoustic guitar piece that plays during in Faraway Town in the evening, signifying the end of a long day and some peace after any troubles that may have occurred earlier. A more somber reprise on piano, [[https://omori.bandcamp.com/track/crossroads Crossroads]], plays as Sunny awakens in Memory Lane and starts on the path to accept the truth.

* [[https://omori.bandcamp.com/track/flouring-with-you Flouring with You]] is an upbeat track uses a soundfont very similar to what you get from ''Franchise/TouhouProject''. You'll notice when the [=ZUNpets=] kick in as Life Jam Guy [[CurbStompBattle toasts your party in one hit]].
* [[https://omori.bandcamp.com/track/chaos-assembly-2 CHAOS ASSEMBLY]] is a fantastic robotic-sounding track that feels too great for a fight against a ''[[BigLippedAlligatorMoment Download Window]]''.
* [[https://omori.bandcamp.com/track/you-were-wrong-go-back-2 You Were Wrong. Go Back.]], a fitting theme for [[WakeUpCallBoss Space Boyfriend]]. This high-tech tune is perfect for letting the GenreSavvy player know that they shouldn't idly mess with this guy.
* [[https://www.youtube.com/watch?v=Pe---DN2TmY You Cannot Go Back]], which plays against Space Ex-Husband in the Hikkikomori route, is a more sinister remix of "You Were Wong. Go Back", complete with a DarkReprise of his mixtape.

* [[https://omori.bandcamp.com/track/swirly-1000x Swirly 1000x]] starts playing in high gear to remind you that you're heavily outnumbered and are in for a rough time.

* [[https://omori.bandcamp.com/track/goldenvengeance GOLDENVENGEANCE]] builds up as Pluto's expanded form slowly enters the scene, and its main melody kicks in when you gain control of the battle interface. This showdown for the freedom of your party from Mr. Jawsum is ''on''.
* Much like GOLDENVENGEANCE, [[https://omori.bandcamp.com/track/underwater-prom-queens Underwater Prom Queens]] has a calm, mystical-sounding intro as it pans over close-ups of the three Slime Girls... then the beat drops as soon as you get to the battle interface and you know the Slime Girls mean business, and they've got enough tricks to keep you on your toes.
* [[https://omori.bandcamp.com/track/tee-hee-time Tee-hee Time]], the theme for Perfectheart, is as wild as that of her clone Sweetheart, but it throws in electronic tones that don't sound out of place in an extremely hard arcade RhythmGame, and goes perfectly well with her status as a {{superboss}}.
* The track for [[https://www.youtube.com/watch?v=zDAPRmM1GN8 the bonus boss fight against Omori's Headspace friends]] is a playful chaotic mixture of several previous tracks, between "[[https://omori.bandcamp.com/track/splintered-sweets-in-the-castle Splintered Sweets in the Castle]]", "[[https://omori.bandcamp.com/track/tussle-among-trees Tussle Among Trees]]", and even "My Time".

** [[https://www.youtube.com/watch?v=PqQC_gl5k0w GOLDENVENGEANCE]] builds up as Pluto's expanded form slowly enters the scene, and its main melody kicks in when you gain control of the battle interface. This showdown for the freedom of your party from Mr. Jawsum is ''on''.
** Much like GOLDENVENGEANCE, [[https://www.youtube.com/watch?v=7xl5kRE19y4 Underwater Prom Girls]] has a calm, mystical-sounding intro as it pans over close-ups of the three Slime Girls... then the beat drops as soon as you get to the battle interface and you know the Slime Girls mean business, and they've got enough tricks to keep you on your toes.
** [[https://www.youtube.com/watch?v=n9gm9lP_4Gk Teehee Time]], the theme for Perfectheart, is as wild as that of her clone Sweetheart, but it throws in electronic tones that don't sound out of place in an extremely hard arcade RhythmGame, and goes perfectly well with her status as [[SNKBoss one of the toughest bosses in the game]].
** [[https://www.youtube.com/watch?v=6rWV5JRd4zA Your Catastrophes - Procession]], the theme for the second phase of the Basil fight. The haunting bells in the piece take an already spooky theme and dials it up to 11, making this theme feel right at home in a ''VideoGame/{{Castlevania}}'' game. Fitting as Sunny suffers a [[FreakOut nervous breakdown]] and brutally fights back against Basil.
** [[https://www.youtube.com/watch?v=W766EABGHe8 OMORI]], the FinalBoss theme, is perfect SadBattleMusic. If OMOCAT wanted to portray the tragedy of [[HopelessBossFight fighting a losing battle against the personification of your suicidal ideation]] through music, then OMORI succeeds with flying colors.
** [[https://www.youtube.com/watch?v=bKC8qqqLZ6A OMORI - ALTER]], an alteration of "OMORI". It suddenly kicks in without warning the first time Omori inflicts the Afraid status on you. It features "OMORI" in the background being drowned out by chaotic noise as Sunny desperately but hopelessly tries to hold onto himself while Omori gets stronger and stronger.
