The sitar is a Hindustani classical instrument. Acoustic sitars typically have a gourd acting as the resonating chamber. A distinctive feature are the curved frets, which are moveable (allowing fine variation in tuning) and raised (so that resonant, or sympathetic, strings can run underneath the frets, giving a very lush sound). A typical sitar has 18 or 19 strings (depending on the style) — there are 6 (in the Vilayat Khan style) or 7 (in the Ravi Shankar style) playable strings on top and 11 or 12 sympathetic strings or tarbs under the frets. It is rather difficult to tune the instrument. The strings can be tuned using both the pegs on the sides or the 'beads' at the bottom, which are mainly for fine tuning.

Etymology
The origin of the name, sitar is most likely from the Persian, like much of north Indian music terminology. The corresponding Persian name is setar, meaning three strings, although there are significant differences between the setar and sitar, suggesting that the sitar developed later and is possibly a direct descendent of the setar (it is also quite likely that the sitar is an adaption of the much older Indian instrument the rudra veena). This is one of many instruments in the lute family of Persian instruments, included among them is the barbat, from which the Arabian oud is most likely derived. (The name lute itself being derived from Al-Oud, via contact of the Arab empire with Europe).
History
The dominant hand is used to pluck the string using a metalic plectrum called the mezrab. Traditional approaches to learning the sitar involve a long period of apprenticeship under the tutelage of a master although nowadays it is possible to purchase books and videos to assist home learning. The sitar became popular in the West when The Beatles used it in "Norwegian Wood (This Bird Has Flown)", "Love You To", and "Within You Without You". Beatles guitarist, George Harrison, was inspired by — and later taught by — Ravi Shankar. Rolling Stones guitarist Brian Jones also helped popularise the sitar among Western musicians, most notably in the song "Paint It Black".
Learning to play the sitar is a difficult process. The entire 3 octave range of the instrument is achieved by sliding the index finger of the left hand up and down the neck of the sitar over a single melody string, while the mezrab on the index finger of the right hand strikes the string. Thus it demands a very high degree of technical mastery to play even simple melodies with clarity and accuracy. It is also a rather painful process for the beginner until the hard calluses and black grooves on the tips of the index and middle finger, which typify the sitar player, begin to develop. A specialised technique called "Meend" involves pulling the main melody string down over the bottom portion of the sitar's curved frets, with which the sitarist can achieve a 7 semitone range of microtonal notes. Meend gives the sitar its characteristic fluid sound, but typically takes the sitarist a decade or more of hard practice to achieve with fluency and precision.
In one of the more common tunings (used by Ravi Shankar among others) the strings are tuned C C G C G C F. The sympathetic strings are tuned depending on the raga, although for beginners it is acceptable to tune them according to a C major scale: C, D, E, F, G, A, B, C, D, E.
When playing sitar, the thumb of the plucking hand should stay on the side of the fretboard just above the main bowl, the plucking arm should carry all of the wieght of the sitar by applying pressure to the main bowl with your elbow and other arm muscles, the fingering hand should move freely without having to carry any of the weight. Generally only the index and middle fingers are used for fingering.
The sitar is instrument #105 on a General MIDI bank.
A 1998 Eurodance song by Jonny Jakobsen (Dr. Bombay) was titled "My Sitar" and the lyrics refer to the playing of the instrument.
