An experimental musical instrument (or custom-made instrument) is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument.
 Some are created through simple modifications, such as cracked drum cymbals or metal objects inserted between piano strings in a prepared piano.
 Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs.
 Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
A sound box or sounding box (sometimes written soundbox) is an open chamber in the body of a musical instrument which modifies the sound of the instrument, and helps transfer that sound to the surrounding air.
 Objects respond more strongly to vibrations at certain frequencies, known as resonances.
 The frequency and strength of the resonances of the body of a musical instrument have a significant impact on the tone quality it produces.
 The air inside the chamber has its own resonances, and these interact with the resonances of the body, altering the resonances of the instrument as a whole.
 The sound box typically adds resonances at lower frequencies, enhancing the lower-frequency response of the instrument.
A musical instrument is an instrument created or adapted to make musical sounds.
 In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument.
 The history of musical instruments dates to the beginnings of human culture.
 Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony.
 Cultures eventually developed composition and performance of melodies for entertainment.
 Musical instruments evolved in step with changing applications.
The Institute of Musical Instrument Technology is the main professional body for all musical instrument makers, tuners and repairers.
 It was inaugurated on 24 February 1938 and was incorporated on 13 March 1961.

The Omnichord is an electronic musical instrument introduced in 1981 by the Suzuki Musical Instrument Corporation.
 It typically features a touch plate, and buttons for major, minor, and 7th chords.
 The most basic method of playing the instrument is to press the chord buttons and swipe the touch plate with a finger or guitar pick in imitation of strumming a stringed instrument.
 Originally designed as an electronic autoharp substitute, the Omnichord has become popular as an individual instrument in its own right, due to its unique, chiming timbre and its value as a kitsch object.
The Red Violin (French: Le Violon Rouge ) is a 1998 Canadian drama film directed by François Girard and starring Samuel L. Jackson, Carlo Cecchi and Sylvia Chang.
 It spans four centuries and five countries as it tells the story of a mysterious red-coloured violin and its many owners.
 The instrument, made in Cremona in 1681 with a future forecast by tarot cards, makes its way to Montreal in 1997, where an appraiser identifies it and it goes to auction.
 The film was an international co-production among companies in Canada, Italy, and the United Kingdom.
The khuuchir is a bowed musical instrument of Mongolia.
 Formerly, the nomads mainly used the snake skin violin or horsetail violin.
 The Chinese call it "the Mongol instrument" or ""huk'in" or "huqin"".
 It is tuned in the interval of a fifth and is small or middle sized.
 The khuuchir has a small, cylindrical, square or cup-like resonator made of bamboo, wood or copper, covered with a snake skin and open at the bottom.
 The neck is inserted in the body of the instrument.
 It usually has four silk strings, of which the first and the third are accorded in unison, whereas the second and fourth are tuned in the upper fifth.
Samick Musical Instruments Co., Ltd. (Hangul: 삼익악기, also known as Samick) is a South Korean musical instrument manufacturer.
 Founded 1958, it is one of the world's largest musical instrument manufacturers and an owner of shares in several musical instrument manufacturing companies.
An electric musical instrument is one in which the use of electric devices determines or affects the sound produced by an instrument.
 Electric musical instruments are an example of electric music technology.
 It is also known as an amplified musical instrument due to the common utilization of an electronic instrument amplifier to project the intended sound as determined by electric signals from the instrument.
 Two common types of instrument amplifiers are the guitar amplifier and the bass amplifier.
 This is not the same as an electronic musical instrument, like a synthesizer, which uses entirely electronic means to both create and control sound.
