The Sitar is probably the most known Indian stringed instrument obtained its present form approximately in the 17th century, although its invention is attributed to Amir Khushru in the 13th century. In the sixties of the 20th century, the instrument gained awareness due to Ravi Shankar and the Beatle George Harrison.
The Sitar consists of a hemispheric soundbox (a processed pumpkin) with a very long neck, which 20 flexible convex frets of metal are fixed. Four playing strings (steel respectively copper) and three bordun strings are strained over the frets. These go over a roughly 2cm board bridge, which is sanded in such a way that a preferably wide overtone spectrum can be hheard. Over the second smaller bridge are under the frets 13 strings (tarif), which get pitched to the actual raga.
The sitar is played with a metal plectrum, which is put on the right hands’s fore finger. The playing strings get ripped on the frets. The tarif strings are plucked with right hand’s little finger’s nail. A second soundbox at the upper end of the concave neck intensifies the sound and rouds it.
