Sitar

Sitar with all its 22 strings and long neck has one of the richest sounds from all plucked strinf instruments.

Some information from Wikipedia:

The sitar is a plucked stringed instrument predominantly used in Hindustani classical music, where it has been ubiquitous since the Middle Ages. It derives its resonance from sympathetic strings, a long hollow neck and a gourd resonating chamber.

Used throughout the Indian subcontinent, particularly in Northern India, Pakistan, and Bangladesh.

The sitar's curved frets are movable, allowing fine tuning, and raised so that sympathetic strings can run underneath them. A sitar can have 21, 22, or 23 strings, among them six or seven played strings which run over the frets: the Gandhaar-pancham sitar (used by Vilayat Khan and his disciples) has six playable strings, whereas the Kharaj-pancham sitar, used in the Maihar gharana ,to which Pt. Ravi Shankar belongs, has seven. Three of these (or four on a Kharaj-pancham sitar), called the chikaari, simply provide a drone: the rest are used to play the melody, though the first string (baajtaar) is most used.

The instrument has two bridges; the large bridge (badaa goraa) for the playing and drone strings and the small bridge (chota goraa) for the sympathetic strings. Its timbre results from the way the strings interact with the wide, sloping bridge. As a string reverberates its length changes slightly as its edge touches the bridge, promoting the creation of overtones and giving the sound its distinctive tone. The maintenance of this specific tone by shaping the bridge is called jawari. Many musicians rely on instrument makers to adjust this.

Materials used in construction include teak wood or tun wood (Cedrela tuna), which is a variation of mahogany, for the neck and faceplate (tabli), and gourds for the kaddu (the main resonating chamber). The instrument's bridges are made of deer horn, ebony, or very occasionally from camel bone. Synthetic material is now common as well. The sitar may have a secondary resonator, the tumbaa, near the top
