Musical Assassin



""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 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.""

- Jim Steinman

Musical assassins are hitmen with style. Who needs guns when you can lay waste to your enemies with a carefully-calculated concerto? Techniques start out at Brown Notes and only get more ridiculous from there. These assassins are especially popular in old Chinese martial arts movies.

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

Compare Magic Music, Disco Tech, The Power of Rock, Make Me Wanna Shout. See also Dreadful Musician for musicians who merely make you wish you were dead, and Instrument of Murder, which is used by musicians for physical attacks. Also related is the Brown Note, which can be used by a Musical Assassin to cause insanity or death. Not to be confused with Assassins, the musical.

Anime and Manga

 * Suite Pretty Cure 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, the magical guitar which turns into a battle ax and shoots exploding rings of magical death.
 * As a Spiritual Successor to the above, Senki Zesshou Symphogear has the leading cast, collectively called "Valkyries", as Magic Idol Singers 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 Limit Break: a solo that creates a near-inifinte amount of strength at the cost of their life.
 * Sphinx Pharaoh (harp), the two Lyra Orpheus and Benetnasch Mime (lyres, though Mime's armor can turn into a harp) and Siren Sorrento (flute) in Saint Seiya. In fact, Mime used to be pictured above. Nice Razor Floss, Mime.
 * Darker than Black features an opera singer who can use resonance to destroy objects and stop hearts.
 * Midvalley the Horn Freak from Trigun uses the music from his saxophone to tear people apart. It also has a machine gun in it.
 * Tayuya from Naruto has a flute that can make illusions and control summoned demons.
 * Digimon Adventure's Etemon used music to control his Dark Network, which can influence anything electronic (including those pesky transformation trinkets, keeping all the Mons stuck at Child level.)
 * Digimon Adventure 02's Archnemon could control insect Digimon with her flute, sending swarms of them as Mooks and temporarily turning Stingmon and Digmon against the rest of the team.
 * Shoutmon of Digimon Xros Wars 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.
 * Kanaria from Rozen Maiden attacks by playing her violin.
 * Nearly every major character in Violinist of Hameln has some sort of music-derived powers.
 * Michiru Kaiou/Sailor Neptune can use her violin to attack her enemies in the manga version of Sailor Moon. Also, Ali from the Makaijuu filler arc 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, Ali tries to summon one randomly and accidentally summons a Cardian that doesn't obey him.
 * In the live-action Pretty Guardian Sailor Moon, 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.,, including a visitor to Tokyo, a picture-book, and a girl who merely ) with effects that range from unexplained sickness to Spontaneous Combustion. Good thing the Big Bad is patient, because  sure doesn't rush the process.
 * Amy/Sailor Mercury plays a harp to perform her Mercury Aqua Rhapsody, which attacks the enemy with water.
 * In Mononoke one of the monsters uses a shamisen (Japanese lute) to inflict dangerous hallucinations on the unlucky humans it comes across.
 * In Katekyo Hitman Reborn, one minor villain - M.M. - uses a clarinet that functions as a microwave, by using sound vibration to agitate water molecules and thus rapidly heating objects.
 * Neon in Flame of Recca uses a Madogu in the form of a flute that manipulates sound waves.
 * Kidaf Gillot from Scrapped Princess used an instrument to command bugs for assassination.
 * The finale of the first Lupin III manga series has Lupin up against a conductor whose assassins and explosives are in sync with his music.
 * Shiho Munakata's Element in Mai-HiME is a flute that lets her control sound waves and give orders to her CHILD, Yatagarasu.
 * Lena from Shamanic Princess has a flute as her main weapon.
 * 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 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 bass solo . And wins.
 * Shirabe of Mahou Sensei Negima who is also a Dreadful Musician.
 * In Fushigi Yuugi, can use flute music to soothe, hypnotize, and even kill people.
 * The Black Beauty Sisters in Mermaid Melody Pichi Pichi Pitch sing to stun the Mermaid Princesses. Likewise, Yuri plays a piano.
 * The Winged Ones in Pure sing as well with various effects. Lady Bat can put his victims to sleep, Lanhua can split into twelve mini-musicians and force her listeners to dance until they die, and Alala can shoot stars that strike her targets.
 * A villain in Speed Grapher would count as one of these; when he used his powers, his body essentially turned into a speaker system.
 * Fou Lafine of B't X, whose Weapon of Choice 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.
 * Early on in 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 Read or Die OVA.
 * Bleach has the Visored Rojuro "Rose" Otoribashi, who can kill you by playing his electric guitar.
 * One Piece has 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 drumbeats that dismember people, and cymbal crashes that cause explosions?
 * A lesser example is Brook. His Lullaby: Flan is where he plays the violin with his sword. It puts everyone in earshot asleep.
 * Soul of Soul Eater uses his skills as a pianist and general musical knowledge in order to, well, orchestrate the black blood and control his own insanity to increasingly devastating effect.
 * Also, when he and Maka were fighting Arachne,
 * In Hunter X Hunter, 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 Dance Battler as this is how he plays himself.
 * Fairy Tail has two. Vithaldas, a freakish rocker modelled 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 giant wooden demon.
 * Florsheim once used a musical assassin monster with a paralysing flute in Tentai Senshi Sunred. Sunred kicked him in the shins and made fun of him, ruining his concentration.
 * Soul King Brooke of the Straw Hat Pirates from One Piece. Somewhat averted in that his music doesn't outright kill, it does however allow him to hypnotize people, allowing him to take them out more easily.
 * Macross 7: "LISTEN TO MY SONG!"
 * Azami from Weiss Kreuz uses a violin as his weapon.
 * In Pokémon, music is an instrumental part of Nando's battle style.

Comic Books

 * Flash 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 antagonist seemingly destined to cause The End of the World as We Know It in the first arc of the comic series The Umbrella Academy is the appropriately-named White Violin. Popular instrument for killing people, isn't it?
 * 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 Usagi Yojimbo story featured a series of killings with a flute-playing ghost as the primary suspect.
 * Johnny Guitar and Dr. Sax in Avengers: The Initiative 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 Tomorrow Stories' Greyshirt happens to be a Mad Scientist in addition to a violinist - and attempts to use his sinister music to prove his long-mocked theories true.

Fairy Tales

 * The Pied Piper of Hamelin: 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.

Fan Fiction

 * Used in Manchester Lost, as a cross between this and the Power of Rock. Beating up Satan with nothing but Don't Stop Believing by Journey, albeit performed by Archangels.
 * In The Graduation Class, a Discworld fanfic in which the author has several characters who fall into the Ascended Extra category, after their names are given in canon, one with a very slight elaboration. And they are all Assassins. This trope was used by Emmanuelle des deux epées from Quirm who kills someone by playing a certain set of cords on a cello, firing a crossbow bolt.

Film

 * The blind musicians (well, only one of them was blind) in Kung Fu Hustle can tear people apart with their music, 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.
 * Wild Zero 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 POWER OF ROCK AND ROLL.
 * The low budget movie Six String Samurai sums it all up in the title. Most of the characters are this.
 * In Scott Pilgrim vs. the World 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.

Literature
"Seven hundred chanting kindergarten children achieved satori and began to eat a huge American flag drenched in soy sauce."
 * In Isaac Asimov's Foundation series, the character of 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 Alan Dean Foster's 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 Simon R. Green's Deathstalker books, there's the rogue Investigator Topaz, of the "Siren" class of esper, who kills by singing. She took out the five hundred men chasing her with one song.
 * Michael Moorcock's 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 Norman Spinrad'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.


 * In Terry Pratchett's Discworld each Nac Mac Feegle clan has a bard whose music can be used in combat.
 * And Death can kill all of reality with a single, well-plaid strum.
 * The Jennifer Morgue and The Fuller Memorandum by Charles Stross have a secret agent with a violin specially tuned to kill demons. 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.
 * 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 Patrica McKillip's The Riddle Master of Hed Trilogy.
 * In The Old Kingdom, 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 Evil Overlord and Evil Sorcerer, the Black Jester, was noted for assembling orchestras and choirs for this precise purpose, so skilled they could wipe out whole cities; Prince Robert in the present storyline is also fond of this technique, with the added bonus that he's immune
 * The 'death flutes' of the Zoromen in the Doc Savage novel Murder Melody can induce either unconsciousness or death in the listener depending on the tune played.
 * Erica Hayes's Shadowfae urban fantasy series features a variety of supernatural beings getting involved in a crime-ridden underworld, including vampires, succubi and various types of fae. In this setting, banshees have magical voices that can cast spells through song, shatter glass or physically harm/kill enemies with a scream, and persuade/seduce humans. They have 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 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.

Live-Action TV

 * Doctor Who: An improvised musical weapon features in "The Lazarus Experiment", when the Doctor uses a church organ to kill the Monster of the Week, who is stretching his mass very thin.
 * Musical weapons are the gimmick of Kamen Riber Hibiki, where they use the ultrasonic vibrations of their music to shatter the Monster of the Week. 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.
 * British sketch show That Mitchell and Webb Look featured one skit with a green clarinet that made its targets sing and dance an embarrassing truth about themselves. It could only be countered by
 * Lorne from 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.
 * In The Middleman, 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.
 * Zen-Aku from Power Rangers Wild Force.
 * Dr. K of Power Rangers RPM has twice fended off a killer cyborg by using her mad violin skillz. Let's not forget the original weaponized instrument, the Dragon Dagger. Of course, this is more of a dagger with a flute design, so...
 * In The Goodies episode "The Stolen Musicians", singer Cilla Black is capable of literally 'bringing down the house' with her singing voice.
 * The 60's 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 a weapon.
 * Sweet, from Buffy the Vampire Slayer: "Once More With Feeling" could use his singing to make people dance to the point where they caught fire.
 * In 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
 * In the ''Friday the 13th: The Series "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.

Religion & Mythology

 * Older Than Feudalism: The Sirens in The Odyssey sang so beautifully sailors dashed ships on the rocks around them.
 * 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.
 * Another lethal fiddler appears in the last part of the Niebelunglied (The source material for Wagner's "Ring Cycle"), although this one used his fiddle bow as a sword and was one of the "greatest heroes" who followed dead Siffrid's wife to Austria.
 * 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.

Tabletop RPGs

 * In the 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 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 'good' side, we have the Exorcist of the Sisters of Battle, the holy fusion of a Macross Missile Massacre and a pipe organ.
 * In the background novels of the "Horus Heresy" series, the Space Marines encounter Warsingers, leaders of a xeno race who use their song (literally) to kill even 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.
 * 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 Celestial martial arts style based on this trope: the Silver-Voiced Nightingale Style.
 * The Bard from Dungeons and Dragons 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.
 * Weapons Of The Gods has a martial arts style called Music of War which lets you attack and debuff enemies from a distance by playing a musical instrument.

Theatre

 * 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.

Video Games

 * The Bard class from the various Final Fantasy games uses a variety of instruments, the most popular of which is a trusty harp. Sometimes they induce Standard Status Effects, but the chances of doing so are very low. Because of this, they're often also a Spoony Bard.
 * In Final Fantasy V 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.
 * Final Fantasy IX 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 White Magician Girl.
 * Also subverted in this manner in Final Fantasy Tactics Advance and Final Fantasy Tactics A2, 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 Final Fantasy Tactics A2, "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.
 * Demyx in Kingdom Hearts II is armed with a deadly sitar. Scared? You will be.
 * Ironically he is also one of the least cruel, laziest, and nicest Organization XIII members, so not only will you hate him for being a hard boss, you will most likely feel immensly guilty for erasing him from existence afterwards.
 * As a bonus, if you listen carefully, you can actually hear the tune coming from the sitar. You know, past the sounds of gallons of water being used to attack you.
 * Birth by Sleep 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.
 * I-No from Guilty Gear 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.
 * Yurika Kirishima from the Rival Schools sequel Project Justice is a subdued variant, her signature weapon being a violin.
 * Her Manipulative Bastard brother Kurow is also an example, using his flute to brainwash victims.
 * Vulturon the Condoroid of Mega Man ZX 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 Mega Man Zero 4 did something of the sort. At least, one of his attack calls is "Sound...dance!"
 * Harp Note from Mega Man Star Force. Contrary to her name, her weapon is more like a guitar.
 * Shade Man's Noise Crush in Mega Man 7.
 * In Gungrave: Overdose, the rockabilly Rocketbilly Redcadillac (yes, that's his name) implies that he was once one of these assassin types. Now, though, he's The Atoner and a ghost, possessing an electricity-shooting guitar.
 * In Devil May Cry 3, Nevan, a succubus boss character, 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 SSStylish combos if used properly. It electrocutes enemies by shooting lightning at them and summoning bats to attack them.
 * Command & Conquer 3 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.
 * Tiberian Sun also has the sonic tank, which is the prototype of the above-mentioned weapon.
 * Zhen Ji in Dynasty Warriors (except the sixth installment) uses flutes for sound waves. In 7, she is joined by Cai Wenji, who uses a harp.
 * Sister series Samurai Warriors has Motochika Chōsokabe, who wields a shamisen (a Japanese guitar, more or less).
 * Super Smash Bros.. 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; Jigglypuff and Peach put enemies to sleep with song; Luigi uses a dance number to summon the Negative Zone; and King Dedede has a song and dance summon Big Gay Dance.
 * Touhou doesn't have just one of these, it has 3: The Prismriver Sisters, each one 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.
 * Mystia's songs make you blind.
 * This example is also unique in that it's also got a bit of realism, sound doesn't miss.
 * Eternal Fighter Zero has Mizuka Nagamori, who can create exploding music notes with her cello.
 * Chrono Cross 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.
 * God Hand: one of the bosses is a guitarist. With lightning projectiles. And he has a return battle where he pulls in a drummer, too.
 * Lyude from Baten Kaitos: 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."
 * In Donkey Kong 64, 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).
 * Sona from League of Legends 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.
 * Cornet from Rhapsody: A Musical Adventure uses her horn as a weapon, although it's more often the channel through which she controls her helpful puppet/monster friends.
 * Monster Hunter games of late have adopted a Hammer subclass called the Hunting Horn, which induces Standard Status Effects 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.
 * Pokémon. 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. And then there's Meloetta. This Legendary uses mostly sound-and-music-based moves.
 * There's enough sound-based moves to warrant the Soundproof ability (which blocks them outright).
 * 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. Deceased Crab, 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. .
 * Ephemeral Fantasia may as well be called 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.
 * There's a mod for Neverwinter Nights 2 actually called Lute Hero. It makes you play a Guitar Hero style rhythm game which is used to power your spells in combat. It has to be seen to be believed.
 * One of the bonus weapons in Castlevania: Curse of Darkness 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.'
 * The Suikoden series also have this trope. Particularly the DoReMi Elves that attacks by singing a note, and Cornelio in Suikoden V who uses a conducting baton.
 * In Luminous Arc 2, the Brilliant Witch, Dia, uses a conducting baton as a weapon. Kaph, who later joins the party, subverts this trope with a guitar...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 Accordion Thief of Kingdom of Loathing have various accordions as weapons, and there are plenty of ranged weapons that are musical instruments.
 * Many, many instruments -- accordions, banjos, drums, guitars, flutes, horns, and one axe-type weapon -- have hit messages that are this, Instrument of Murder, subversions or double-subversions of either/both.
 * One of the many frankly insane weapons in the Aqua Teen Hunger Force spin-off golf/combat game, Zombie Ninja Pro-Am, alongside the chainsaw, golf club and sword, is the Red Electric Guitar. Rather than hitting your opponent with it, you can stun and injure enemies ranging from 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 Atlantica Online uses a guitar as a weapon. Despite very obviously being an acoustic guitar, it makes electric guitar noises, likely because of Rule of Cool. The same reason there's a class that uses what appear to be modern chainsaws in an apparent pre-20th-century Anachronism Stew setting -- there were Chainsaws in the 19th century, but they don't look anything like what a modern viewer would expect.
 * The whole battle system of 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.)
 * also counts, using off-key music as an attack.
 * A mod for Doom lets you use 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!
 * The whole point of Space Channel 5 and its sequels.
 * Also the whole point of Gitaroo Man.
 * The Legend of Zelda: Majora's Mask gives us Sharp and his Melody of Darkness, which slowly drains Link's health away.
 * Most of Achmed Khan's special moves in Backyard Skateboarding live off this trope (and an Air Guitar).
 * One SpongeBob SquarePants 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 Lego Rock Band 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.
 * Nightmare Before Christmas Oogies Revenge 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.
