surbahar

Surbahar (; ) sometimes known as bass sitar, is a plucked string instrument used in the Hindustani classical music of the Indian subcontinent. It is closely related to the sitar, but has a lower pitch. Depending on the instrument's size, it is usually pitched two to five whole steps below the standard sitar.

==Overview== The surbahar is over 130 cm (51 inches). It uses a dried gourd as a resonator, and has a neck with very wide frets, which allow a glissando or "meend" of as much as an octave on the same fret through the method of pulling. The neck is made out of toona, or mahogany wood. It has 3-4 rhythm strings (chikari), four playing strings (the broadest 1 mm), and 10 to 11 sympathetic strings. There are two bridges; the playable strings pass over the greater bridge, which is connected to the tabli with small legs, which are glued in place. The sympathetic strings pass over the smaller bridge which is directly glued on the tabli (soundboard). The bridges have a slightly curved upper surface parallel to the string that the strings touch when vibrating, which results in a buzzing sound known as jawari. The body of the instrument is similar to that of a sitar, in that it is made of a large dried gourd with a carved wood face on one side and joined to the neck by a carved wooden yoke or "gulu". It differs in that most surbahars have a gourd that is larger and tilted 90º so that the bottom of the gourd is to the back of the instrument, creating a shallower and rounder body for an enhanced bass response.
