Instrument of Murder



"Mexican Bandito: Tell me, Kabong, what do you use? A sword? A whip? A shillelagh? El Kabong: I use a gee-tar! Kabong! (kabongs bandito)"

- Quick Draw McGraw

So you're an assassin who is also a musician. Unfortunately you're not a Musical Assassin and cannot kill people with the power of your music alone. So what are going to do? Why, have a musical instrument that doubles as a deadly weapon of course. A step up from Senseless Violins, with no danger of your weapon being discovered if anyone opens your case.

This trope covers weapons hidden in musical instruments. For assassins who kill their targets with music, see Musical Assassin. For weapons used as instruments, see Instrumental Weapon.

Anime & Manga

 * Midvalley the Hornfreak in Trigun is mostly a Musical Assassin who tears it up with sound waves from his saxophone, but it's also a complicated firearm that he eventually
 * The chancellor of Alabasta in One Piece also used a firearm/saxophone as his weapon of choice.
 * M.M. in Katekyo Hitman Reborn uses vibrations from her clarinet to microwave and melt things. In a pinch, she can also hit people with it.
 * Haruko from FLCL wields a pull-string-ignition bass guitar. It can also blast doors in half with some kind of firearm function. It's more a question of what Haruko can't do with her guitar.
 * Genkaku the Hypermonk from Deadman Wonderland has a guitar that can split into a pair of machine guns. Or, alternately, it turns into a gun capable of punching head-sized holes through people. Take your pick.
 * Scrapped Princess has the Silencer, an assassin who can summon and control deadly insects with an instrument.
 * In Saint Seiya, the Asgardian God Warrior Benetnasch Eta Mime, wears a Cloth reminiscent of a harp. As such, he is prone to laying down Razor Floss around the environment as traps, as well as send them flying towards his opponents to entangle them. Note that his harp's strings are strong, and sharp enough, to crack and cut through solid rock, as well as Bronze Cloths and the very human skin of the Saints wearing them.
 * A normal sized violin in Violinist of Hameln: Shchelkunchik.
 * Sailor Neptune's final attack in the manga version of Sailor Moon, Submarine Violon Tide, is - you guessed it - an attack using her violin. She also whips it out earlier on in the Infinity Arc and incapacitates the Inner Senshi. Sailor Mercury, meanwhile, uses a watery lyre for her final attack, Mercury Aqua Rhapsody.
 * Samurai Champloo: In the first part 'Hellhounds for Hire' Jin is disguised as a woman carrying a biwa (a traditional Japanese instrument similar to a guitar).

 * Shattered Angels has one of these in the form of the Mana Buster, a modified cello that provides fire support during the final showdown.
 * Gintama: The character Kawakami Bansai can use the strings from his shamisen to restrain people.

 * Cure Lemonade from Yes! Pretty Cure 5 also uses castanets, which is odd, because her teammate, Cure Mint, is an Expy of Mew Lettuce. Also from the Pretty Cure series we have the Pine Flute, the Passion Harp, the the Shiny Tambourine, and the Love Guitar Rod.
 * Haji from Blood Plus borders on this trope. He regularly uses his cello case as a weapon/shield. The cello itself is only used to perform music. One does have to wonder how it hasn't been smashed to pieces inside his case though.
 * Fullmetal Alchemist: Catherine Armstrong uses a piano to attack Yoki when he tries to steal money from the Armstrong family. Given her Super Strength, That Has Been Passed Down Through The Armstrong Family For Generations.
 * Blade of the Immortal: The ridiculously skilled Makie Otono-Tachibana, who specializes in Waif Fu, wields a double bladed three-section-staff called Haru-no-Okina concealed in a hollowed-out shamisen, a mandolin-like Japanese instrument which she is able to play when not slicing and dicing her enemies.

 * In The Tragedy Of Y (Ellery Queen writing as Barnaby Ross), one of the murder victims is smacked in the face with a mandolin. (Twisting this trope a bit, the blow wasn't fatal, but did set off a fatal heart attack.) This turns out to be a clue to the murderer's identity.
 * In Juliet Marillier's Bridei Chronicles, Faolan is a musician and an assassin, and he strangles someone with a harp string at one point.

As the bad guys learn the HARD way, with it's maximum output focused on a person, it can knock them out with horrible stench, blow their eardrums out and not only blind them with a laser, but set them ablaze.

Live Action TV

 * Ibuki of Kamen Rider Hibiki has a gun that can transform- by shifting the parts around- into a trumpet. It actually works in reverse from normal: he uses the gun to implant bullets in the Monster of the Week (who is naturally Immune to Bullets) then switches to the trumpet to create a resonance that blows it up.
 * All of the Riders use these. Hibiki straps a taiko drum to the monsters and proceeds to beat them to death with taiko drumsticks (and even without the drum, the drumsticks can shoot fireballs), and Todoroki uses an electric guitar that doubles as an ax.
 * It can get fairly silly with some of the minor Oni Riders, who use weaponized tubas and triangles.

 * One enemy agent in The Avengers had a clarinet with a blade that would slide out of the bell when the right key was pressed. He used it twice: once to kill a fellow he caught trying to steal the McGuffin, and once in an unsuccessful fight with Steed ... who remarked that the instrument probably played "sharp."
 * In Community episode English as a Second Language Chang wields a key-tar like a battle axe.

Mythology

 * Greek Mythology time: According to one myth, the lyrist Linus was the music teacher to Hercules. After criticizing Hercules' playing a bit harshly, Herc took Linus' lyre and bashed its owner's head in. The first evidence of this story is in vase-paintings of the 5th century BC, making this one Older Than Feudalism.

Professional Wrestling

 * Professional wrestler Jeff Jarrett would occasionally indulge in smacking his opponents with a nonfunctional guitar.
 * Before J-A-Double R-E-Double T, there was the Honky Tonk Man. Though the whole "smack you with the guitar" thing took a nasty turn when Honky hit Jake "The Snake" Roberts with a real guitar and severely injured him -- which was the beginning of Roberts' many problems with painkillers.

Real Life

 * The shakuhashi (Zen bamboo flute) of Japan is a bit of a subversion; initially it was just a normal flute, no military applications attached. However, when the samurai that normally used it became unemployed and unable to use their swords by law, they beefed the flute up to be strong enough to be used as a club, thus becoming their main weapon of defense.
 * A sufficiently large hard instrument case works as a decent Improvised Weapon, if you're not too worried about the instrument inside. Actually, scratch the "sufficiently large;" it hurts plenty to be hit in the head with a flute case.
 * And then there's the 1812 Overture. No less than 16 cannon shots are written in that piece.
 * ACDC incorporated cannons into their stage act for "For Those About to Rock".
 * Also by AC/DC, the cover for If You Want Blood You've Got It.

 * Gene Simmons bass looks like an axe. Unfortunately it only functional as a bass.
 * The shawm (an ancestor of the oboe) was used as a weapon from time to time.
 * An unspecified spy service apparently at least once modified a flute to fire a single pistol round. The instrument was still fully functional for musical purposes.
 * The Clave: http://www.trsdirect.com/ Although listing this as real life could be a stretch.

Tabletop Games

 * Noise Marines in Warhammer 40000 can do this. If blasting the enemy with The Power of Rock doesn't work, they can simply beat the enemy to death with their daemonic, spiky guitars and superhuman strength.
 * The Exorcist applies this principle to a pipe organ... then attaches it to a tank. Too bad the Exorcist couldn't hit the broadside of a Titan.
 * In Silver Age Sentinels, Feedback is a rock star turned superhero who wields a guitar that focuses his powers into energy blasts.

Video Games

 * Eiko from Final Fantasy IX used a flute as a weapon - both by whacking people with it and by playing it as part of her Summon Magic.

 * One of the joke weapons in Disgaea 4: A Promise Unforgotten is an electric guitar.
 * Certain classes in Final Fantasy Tactics Advance and Final Fantasy Tactics A2 can equip musical instruments as weapons. There's nothing particularly clever about how they use them in combat though: they just bludgeon the enemy over the head. Like the books, staffs and rods, you're generally supposed to assume that said items are primarily used as tools for casting skills, and not bludgeoning weapons.
 * In Final Fantasy Tactics, Bards could use harps to deal ranged damage that appeared to be the notes causing the damage. Bard Songs were typically of the beneficial variety.
 * I-No of Guilty Gear uses a shapeshifting electric guitar. She can either smash people with it, or create cacophonic sounds to defeat her opponents.
 * Zhen Ji of Dynasty Warriors 4 and DW 5 has a flute as her signature weapon. Typically this just means she whacks people with it, but her special attack involves playing a devastating note.
 * Motochika Chokosabe from Samurai Warriors 2/ Warriors Orochi 2 rocks out on his shamisen to attack.
 * Somewhere on the border between this and Senseless Violins, there's a brief cutscene in Shogun: Total War that shows a ninja assassinating his target with a poison dart blown out of a flute.
 * The seventh game in the Touhou series features a stage boss the Prismriver Sisters, a trio of poltergeists who generate their "danmaku" through music. Admittedly, not the straightest of examples, as danmaku is explicitly stated in supplemental material to be non-lethal, but they do threaten to eat prepare as party snacks at least one protagonist, so, yeah.
 * One of the power-ups in Total Overdose are two guitars that act like machine guns, in a clear homage to the Once Upon a Time in Mexico example above.
 * A couple of characters in Eternal Sonata use musical weapons, such as a clarinet/gun/mallet and a fencing rapier shaped like a conductor's baton.
 * Demyx from Kingdom Hearts on top of using his sitar to create water-based minions and cast various water-based spells, he can bludgeon his enemies with it.
 * Equipping Xigbar with the Mystery Gear in 358/2 Days makes him wield a pair of trumpets in the stead of his Arrowguns. They shoot musical notes, accompanied by the appropriate sound effects.
 * In Monster Hunter, Hunting Horn's are almost as effective as hammers at breaking body parts.
 * Rocketbilly Redcadillac's electricity-shooting guitar from Gungrave: Overdose. The artbook says its name is "B.L. 20,000V". ("Blue Lightning 20,000V"). Made by the Electrigger Company! Despite being weak with melee fighting, Billy can do a little dance that causes his guitar to spin around him, bludgeoning mooks.
 * Mizuka Nagamori of Eternal Fighter Zero may prefer to create exploding music notes, but she has no problem bludgeoning you with her cello. Her cello bow can also function as a boomerang.
 * Kaph's guitar doubles as a gun in Luminous Arc 2.
 * From the same game, Sadie, the Breeze Witch, uses a trumpet as a weapon. It's surprisingly effective.
 * Some of the ranged weapons in Kingdom of Loathing are musical instruments that double as weapons.

 * In Brutal Legend Eddie can electrocute people with his guitar.
 * Left 4 Dead 2 allows players to wield an electric guitar as a melee weapon. It makes a satisfying kabong noise when you hit things with it.
 * In Team Fortress 2, the Engineer can now use his guitar as a taunt kill, which uses the same noises from Left 4 Dead 2.
 * Possibly inspired by the shakuhashi from above, Suzume in Mini Ninjas uses her flute both as a close combat weapon and an improvised boat paddle.
 * Though she's primarily a Musical Assassin, Yurika Kirishima of Project Justice is not below using her prized violin as an épée when in combat.
 * The Arcanite Ripper of World of Warcraft fame is an axe that doubles as a guitar.
 * The AI Weapons in Metal Gear Solid: Peace Walker are primitive Vocaloids put into big, heavily-armed tanks.
 * Bards and their more powerful counterparts in Ragnarok Online fight with their musical instruments. What doesn't entirely make sense is how they manage to throw/shoot arrows (depending on the skill) by swinging it at their opponents. They can also be Musical Assassins by spamming songs, but it takes more effort, mana, and time.
 * Kimmy Howell of No More Heroes 2: Desperate Struggle has a flute that turns into a double-ended Laser Blade.
 * ANYTHING can be used as a weapon in Dead Rising. Guitars and other musical instruments count as "anything".

 * The Hero from Ephemeral Fantasia has a sword hidden in a guitar.

 * There was an old Christian-themed computer game (called Knights Of Virtue if I recall) which featured among its weapons the "trump of fire" and "trump of lightning", a pair of trumpets that, if pointed at your enemy and played, wouldn't make a note (just a "ffffff" noise like someone blowing into a tube, fancy that), but would rain down fire or lightning on them.
 * Terraria added a weapon called the Magical Harp. Oddly enough, it can be used to kill The Destroyer in a matter of seconds. Beware the Spoony Bard.
 * Terraria added a weapon called the Magical Harp. Oddly enough, it can be used to kill The Destroyer in a matter of seconds. Beware the Spoony Bard.
