Tanpura is an Indian drone instrument. It resembles a sitar except it has no frets. This instrument has five strings tuned to the tonic. The word "tanpura" (tanpoora) is common in the north of India, but in south India it is called "tambura", "thamboora", "thambura", or "tamboora". The tanpura is known for its very rich sound. There are three main styles; the Miraj style, the Tanjore style and the small instrumental version sometimes called tamburi. In recent decades the tanpura has become popular. Its most striking characteristic is its size. It has a very shallow resonator made of wood and only a slightly curved resonator plate (tabali). This is not made of a gourd, but of all wood. It appears to be teak, but we can't be sure. It holds its tune and retains all original binding, fine tuner beads, bone nut and saddle. A great drone instrument to jam along with, or explore as many ragas as possible. The five string version instead of four means more tuning possibilities are possible.
