What is a Shrutibox and how is it played?

The shrutibox (also called sruti box, surpeti or swar pethi) is a perfect accompaniment for modal music, improvisation, voice work, overtone singing, music therapy and all kinds of Indian music. It gives a full, supporting drone sound and is sturdy, mobile and extremely easy to handle. In order to get started you first need to unlock the wooden latches of the bellows on both sides. Next you open the levers for the notes you like to sound. Finally you gently move the open bellows on one side - and there unfolds your drone! Your second hand is not required for playing - it remains free all the time.
