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.
 According to its website, the Institute is the only professional qualification covering the whole field of musical instrument technology.
The Students For Society (SFS) was founded in Panjab University, Chandigarh on September 2010 as a students' discussion group for holding discussions on books and social issues.
 It rejected the politics of muscle and money power by mainstream political parties in University.
 It also rejected the politics of those who were trying to get votes by offering movie shows, dinners, trips and beauty parlour coupons.
 SFS takes out its rallies on foot with singing of slogans with a Tambourine ("Dafli") while other parties took out rallies in cars.
 Its rallies are joined by a considerable number of campus students while the SOI, PUSU and NSUI alliances had to call outsiders in violation of the Lyngdoh panel norms.
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.
Music lessons are a type of formal instruction in playing a musical instrument or singing.
 Typically, a student taking music lessons meets a music teacher for one-on-one training sessions ranging from 30 minutes to one hour in length over a period of weeks or years.
 For vocal lessons, teachers show students how to sit or stand and breathe, and how to position the head, chest, and mouth for good vocal tone.
 For instrument lessons, teachers show students how to sit or stand with the instrument, how to hold the instrument, and how to manipulate the fingers and other body parts to produce tones and sounds from the instrument.
 Music teachers also assign technical exercises, musical pieces, and other activities to help the students improve their musical skills.
 While most music lessons are one-on-one (private), some teachers also teach groups of two to four students (semi-private lessons), and, for very basic instruction, some instruments are taught in large group lessons, such as piano and acoustic guitar.
 Since the widespread availability of high speed.
 low latency Internet, private lessons can also take place through live video chat using webcams, microphones and videotelephony online.
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.
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 tambourine is a musical instrument in the percussion family consisting of a frame, often of wood or plastic, with pairs of small metal jingles, called "zils".
 Classically the term tambourine denotes an instrument with a drumhead, though some variants may not have a head at all.
 Tambourines are often used with regular percussion sets.
 They can be mounted, for example on a stand as part of a drum kit (and played with drum sticks), or they can be held in the hands and played by tapping or hitting the instrument.
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.
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.
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.
