Tanpura
The Tanpura is a drone instrument of Indian music prevalent in both the Hindustani and the Carnatic systems. It plays an important role in a concert of classical music by providing the base note (adharaswara) and by creating an aesthetic ambience on the stage.The tanpura by its function of providing a background, provides neither a specific note nor a rhythm. It creates a circle of certain pitches which by themselves do not produce a melody.
