Introduced by westerners several hundred years ago, the violin is no longer thought of as a foreign instrument, so successfully has it been adapted to the needs of Indian music. In Bengal, it has been used by kirtan groups from whom the Bauls probably picked it up as they did the khol. Strings are usually of metal rather than gut, and are tuned in a common Indian way to low tonic, fifth, higher tonic, and fourth. Just as its tuning, stringing, and repertory have changed in India, so too has its playing technique.
