Again, the fact that the early instruments were harps constructed in the form of a bow lends support to this idea for a harp can easily be imagined as a bow with a number of parallel strings. The 'Villadi Vadyam' has such a use and its very name (villu:bow) indicates its shape and, perhaps, its parentage. One of the commonest assumptions is that the earliest stringed instrument was the hunter's bow. The origin of string instruments are difficult to trace. The chief types used are ' Ektara', Indian sitar, ' Surbahar', ' Swarmandal', ' Tambura', ' Veena', ' Sarod', ' Sarangi', ' Rebab', ' Esraj', ' Santoor' and ' Sarinda'. In Indian music, a number of different types of string instruments are used. In the world of international music, string instruments are usually classified into lutes, harps and zithers. The bowed class appears to be quite old, yet these instruments did not occupy a place in classical music until the last few centuries. Indian music has a rich tradition of string instruments and this class of instruments are all plucked, bowed or hammered ones.

This category of musical instruments referred to as 'Tata Vadya' in Bharata 's Natyashastra, are found in quite a sizeable number in India. String instruments are those which produce sound by being plucked by way of vibrating strings.
