A “shruti box” (also called surpeti) is an instrument predominantly used in Indian classical music that follows the same concept as a harmonium or pump organ. Its design makes use of one or two bellows that push air through tuned metal reeds inside the box. The reeds, which replace keys, are effectively controlled by the performer by opening and closing small flaps to either mute a tone or let it resonate.
