Ominous Music Box Tune

A music box tune that sounds a bit off. It may have an overly cheery or depressing sound to it or the tune just seems to be completely out of place. Either way, the effect is just creepy, and there is something not quite right about it. Something not quite right at all.

Shows up in horror movies and TV shows occasionally.

Compare Ironic Nursery Tune, Creepy Circus Music, and Creepy Children Singing, where creepy songs and nursery rhymes are played in the background to add tension and fear to a scene. Similar to the Uncanny Valley, in that the tiny bit that's "off" is what makes it feel very wrong.

Anime

 * Shinigami Death Punch: The ending theme of Shinigami Death Punch! features lyrics set to a very ominous music box tune.
 * Given the eerie nature of the series, a few of the songs Higurashi no Naku Koro Ni are like this: Kikai, Henka, Hayashi, Giwaku, Hyoui, Tatari, the main theme (not the opening song), etc.
 * The main theme is accompanied by a very distinctive, creepy, subdued sort of wailing, but it may takes one or two times through the series before you notice it's actually . No, seriously.
 * Its sequel has a few as well. The ones that stick out most are "worldend solo" and "Wingless."
 * Elfen Lied: Heji, Lilium, Uso Sora, Katsubou, and especially Yureai. In fact, there's even a physical music box as part of the plot.
 * Neon Genesis Evangelion: The Crime of Innocence, Rei I, M-4 piano, The passage of emptiness, Jesu: Joy of Man's Desiring (which is played in the DVD menu).
 * Kabe no Mukou (The Other Side of the Wall) is played whenever Kaede becomes depressed or slips into insanity, in the anime Shuffle.
 * Vampire Knight: Maria Kurenai's theme.
 * One could also count the music box version of "Still Doll" (the ending song)as well.
 * D Gray Man: Road Kamelot's song, which she sings whilst she makes Marshall Yeegar relive his worst memory over and over and over.
 * The musical watch chime from Noir, which is both very creepy (hint: it triggers all kinds of ugly flashbacks for two of the three Noir candidates) and very ripped off from For a Few Dollars More.
 * Ghost in the Shell 2: Innocence had an entire sequence set inside a very creepy Mind Screw mansion, all accompanied by the world's biggest music box ("The Doll House" versions 1 and 2). The score composer said in interview that he wanted it to sound like you were inside said music box - and he most certainly succeeded.
 * In the Making Of-extras on the DVD it's shown how they did it: they had a company specializing in music boxes make them a huge one to play the tune, and then took it into some empty mine shaft to record it. Sure, they could have just electronically added the echo, but it just wouldn't have been authentic enough.
 * One can be heard at the beginning and ending of episode 11 of Ghost Stories.
 * Whenever England from Axis Powers Hetalia is either trying magic or talking to his supernatural (and invisible to everyone else) friends, one of these is used.
 * One is used at the beginning of Russia's character song "Winter."
 * One is also used in the anime during Russia and Lithuania's first meeting.
 * Russia's theme from the World Series soundtrack, Vodka on a Snowy Night, uses this too.
 * The "Julia" theme from Cowboy Bebop is very reminiscent of a music box up until the penultimate episode where it's sung briefly.
 * Suito Kusanagi in The Sky Crawlers has a large stationary music box in her office, that plays the movie's theme tune. It's probably a Shout Out to the director's previous work, Ghost in The Shell 2: Innocence, mentioned above.
 * Lacie from Pandora Hearts has shades of this. One is also used in episode 10.
 * "Waltz for Strain", the Bootstrapped Theme of Soukou no Strain and the source of many other pieces of BGM in the series (such as Sara's battle theme), has a music box variation, which is probably the most well-known version (it even plays on the official website). It's actually associated with in-story music boxes, too.
 * Averted in Ashita no Nadja, where the music box's Waltz Number 5 melody is actually a cheerful and sweet song.
 * This remix of 'Theme of Puella Magi' from Puella Magi Madoka Magica uses this trope to great effect.
 * From the official soundtrack we have "Conturbatio", (one of) Sayaka's Leitmotif.
 * D.N.Angel: Occurs at the end of episode 20 here when Mio Hio worriedly watches as Daisuke tries to put his key shaped pendant through Riku's heart shaped pendant so that they'll be bonded forever. Also occurs in episode 26 as Dark and Krad are fighting.

Film

 * The music from a musical box entrances the killer into a homicidal state of mind in Dario Argento's Deep Red.
 * The Sandman in Hanna.
 * Davey Jones' music box In Pirates of the Caribbean: Dead Man's Chest. It was supposed to be romantic--because of Davy Jones and, but the effect was kind of ruined when they did that crazy-evil organ arrangement while the fish-pirates were scrubbing the deck.
 * This is also an instance of the planet wide cinematic regulation which says that wistful music-box melodies must slow and eventually stop just before the final note.
 * The above Pirates of the Caribbean example seems like an homage to For a Few Dollars More, where El Indio (sexy weed-smoking Mexican baddie) is addicted to a musical pocket watch, which plays Morricone music, and he uses it every time he has a duel, or just kills someone.
 * As the flashback sequence in throughout the movie keeps extending, showing us more and more of what happened on that rainy night, you realize just how creepy this is, since El Indio got it from a woman whose husband he killed and whom he then raped, driving her to shoot herself. One of the two heroes has a matching version because it turns out the woman was his sister.
 * Used to great effect in their final showdown as they agree to draw when the music stops.
 * Major plot point in Tuck Everlasting.
 * The main theme from Ju-on: The Grudge.
 * Charlie Clouser - Dead Silence, main theme.
 * Samara's song from The Ring.
 * The song that plays in the opening ballroom scene of the Disney movie Haunted Mansion. The music box in the movie also has a similar tune.
 * Hedwig's Theme. Even though it is never heard from a music box, the instrumentation is heavily reminiscent of one.
 * The theme from Candyman is this.
 * One Missed Call has this as a cell phone ring tone and a teddy bear that plays it.
 * The arrangement of "Mother" in the movie Pink Floyd The Wall.
 * Danny Elfman uses this in a lot of his works, for example, in the theme from Edward Scissorhands and Jack's Lament
 * As if there wasn't enough horror motifs in the 1999 remake of The Haunting (it already had Creepy Circus Music), there was also a music box tune which Eleanor was humming almost from the beginning of the movie (suggesting even then that she was already being drawn to the house). She later finds the actual music box in the nursery of Hill House. If it isn't too blasphemous to consider, one might wonder if this is meant to be the tune for the song "Journeys End In Lovers Meeting" from the Shirley Jackson novel.
 * Actually, the "song" from the novel is called Carpe Diem, and it's a poem that Shakespeare wrote for his play, "Twelfth Night."
 * In Time After Time, Jack the Ripper has a cameo on a chain that contains, along with a mystery woman's photo, a tiny music box as accompaniment to his activities.
 * The theme song of Dead Friend (aka The Ghost).
 * The Red Queen's theme from Resident Evil was written to sound like a sweet child's waltz. As the movie continues, her theme becomes increasingly dark and menacing as she shows her murderous colors to the group.
 * Throughout The Innocents, Flora's music box plays the tune O Willow Waly, the lyrics of which are sung by Flora at the very beginning of the film.
 * The first few notes of "Do You Know Where Christmas Trees are Grown" (a cheerful song that played in the background earlier) can be heard in a tense scene after 007 is locked in a cable car machine room in On Her Majesty's Secret Service.

Live Action TV

 * There was a tune like this in the Are You Afraid of the Dark? episode "The Tale of the Dark Music" when the Creepy Doll shows up. There were a more tunes like these in other episodes as well.
 * In the Star Trek the Next Generation episode "The Survivors," Deanna Troi, The Empath of the crew, happens to hear a music box playing during her visit to an elderly couple's home after a mysterious attack on their colony. Her empathic nature briefly brings her into contact with something very powerful that doesn't want to be discovered - the result is that the music box melody starts playing in her mind over and over again, louder and louder, until even a medically induced coma can't block it out.
 * Used in Doctor Who in "Silence in the Library" as the theme for the library and the alternate world, doubling the WTF factor and giving the episode Moffat's trademark 'dark fairytale' overtone.
 * The final notes of the Dollhouse Instrumental Theme Tune sound like a music box in minor key. Appropriate, given the title.
 * The killer in the Babylon Five episode "No Compromises" uses one.
 * Criminal Minds makes use of the very haunting "Illabye" to great effect on two separate episodes.
 * Power Rangers RPM features a haunting tune whenever Dillon (Ranger Series Black) has a flashback of his past prior to the series beginning. The dark lighting in those flashbacks don't help, either.
 * The Ominous Music Box Tune is used to a fantastic effect in this advert for Eastenders.

Music

 * The song "Blue" by The Birthday Massacre.
 * "Grisly Reminder" by Midnight Syndicate.
 * "Sæglopur," by Sigur Ròs, manages to combine this and some of the most haunting bowed guitar ever.
 * Sigur Ros uses music boxes quite a lot, actually, especially in Takk and Ba Ba Ti Ki Di Do. Most of the time the sound is meant to be pretty rather than ominous, however.
 * "Haunted Music Box," Made By Sirfinix.
 * "Kid A" and "No Surprises" by Radiohead.
 * Gothic Lolita by Emilie Autumn starts with a clanky music box tune that jumps notes when you least expect it.

 * "White Russian" by Marillion uses this to chilling effect, even slowing the music box to a halt just before the last note.
 * "Swept Away" by Flyleaf.
 * "Spieluhr" by Rammstein. The title actually means Music Box.
 * Rockabye Baby is a band that does covers of classic rock and alternative songs as instrumental baby music. Their output runs quite a gamut of bands, from the Beach Boys to Bob Marley to Green Day to Tool, so it occasionally runs into this (especially with the covers of Tool, Nirvana, Metallica, Radiohead, and Nine Inch Nails)
 * In The Phantom of the Opera, the music box with the monkey on top plays "Masquerade."
 * "Music Box" by Eminem. As you would expect from Slim Shady, it has some pretty dark lyrics about drug use, satanism, cannibalism and the like.
 * "Return To Innocence Lost" by The Roots uses an eerie music box tune in it's backing music. The effect is meant to be sad rather than scary though; the song is about the child of an abusive drug-addicted father growing up to become an addict himself and eventually dying at a young age from a gunshot wound.
 * "Old" by Starflyer 59 begins with the clicking of a music box being wound. The music box plays for the opening stanza before getting drowned out. It can be heard again at the end, after the other instruments stop.
 * "Jynweythek Ylow"(Cornish for "electronic music machine") by Aphex Twin.

 * The Ambient musician Colleen is fond of the music box. She has an EP full of them.
 * Steven Wilson's song "Significant Other" has this at the end.
 * Porcupine Tree's "Drawing the Line" has one at the start (it's not actually a music box, but still fits the trope).
 * Thrice's "Music Box" features an actual recording of a music box, which the band had to wind just so in order to sync it with the heavy guitar rock of the song.
 * The Northern Kings' version of the Radiohead song "Creep" uses a music box to make the song sound incredibly...well, creepy. This is especially noticeable at the beginning and end of the song, creating an eerie and spooky atmosphere.
 * Hannah Fury loves this trope. It's featured in a large number of her songs, most notably Beware The Touch, My Next Victim and Never Look Back.
 * Used in several song outros on Kaizers Orchestra's album Violeta Violeta Volume I.
 * Korn's song Dead Bodies Everywhere opens with this.
 * Panic At the Disco's Ballad of Mona Lisa

 * In Quest for Glory IV, the music box in the old man's house plays a rather mournful tune and almost certainly belonged to the man's dead wife, who you later meet as a ghost in the forest.
 * In DK64, the tune that plays in Frantic Factory opens with a singularly creepy music-box segment, complete with "winding up," and it returns several times throughout the tune.
 * Just about the entire soundtrack of American McGee's Alice comes off as this.
 * The "Game Over" music in Blaz Blue sounds like a generic, slightly dissonant "better luck next game" tune (mostly "ominous" because the player just lost). Early in Ragna's Story (the first most players are likely to try, since it's at the top of the list), it's revealed to be the song from Saya's music box. Who's Saya, you ask? Figure It Out Yourself.
 * Meteos gives us the theme music for Jeljel.
 * Fable 2 has the music from the music box from the beginning playing during.
 * "Luigis Mansion" especially the remix which actually incorporates a few cords from a music box.

 * Final Fantasy Crystal Chronicles has a song called Mag Mell, which is the theme of a location filled with  that you can only get to
 * The Disgaea games have a "music box" version of Dark Whisper, which plays on the title screen. If nothing else, it's a lot more serene than most of the music one normally hears in the games.
 * In Pokémon Black and White, the BGM for N's Toy Room is this. Whether it's more creepy or sad is up for debate.
 * It's both.
 * N's regular overworld Leitmotif comes off as this as well.
 * The BGM for the Fortune-Teller's room in Shivers.
 * Rise of Nightmares for Xbox 360 Kinect features a hand-cranked musical lock that plays an appropriately creepy tune. Just don't crank too fast or slow...just don't.

Web Comics

 * In Silent Hill Promise Vanessa finds a music box on the roof of the hotel that plays a tune she recognizes.
 * "Clockwork Melody" and "Clockwork Sorrow" from the fifth Homestuck album are versions of the "Endless Climb" song played that come across as this. "Clockwork Contrivance," too, to a much lesser extent.
 * Rose gets one with a mournful violin right after she goes grimdark.
 * No one has mentioned Final Fantasy V yet. Wow. The Music Box song isn't terribly creepy, but the scene that goes with it makes it somewhat depressingly creepy. Here is HCBailly's moment; the music box starts at 4:25

 * Also, this song.
 * One Aladdin episode featured Mirage, the incarnation of evil, using a magical music box that put the entire city under a sleep charm. The tune is quite nice, but also creepy at the same time.
 * A extremely creepy one plays from just off screen in the film Batman Beyond Return of the Joker. Even more disturbing once you realize
