(from Latin ponere: "to place"), in Western music, small organ used in liturgical and, at times, in secular music from the 10th to the 17th century. It had short legs and was set on a table or the floor; two persons with a cart could move it. Two persons were also needed to operate it, the player and a second person who worked hand or foot bellows. There was one manual, or keyboard, and a limited selection of flue (flutelike) stops and, later, reed stops.
