The psaltery has survived through the centuries, from ancient times to the present. Zither Heaven's bowed psaltery features a triangle shape, which separates the strings to form a diatonic scale on one side and the remaining chromatic notes on the other side. Simply designed and easy to bow, the Zither Heaven psaltery is designed for a child interested in music. The psaltery includes tuning wrench, bow, and rosin. Made in the U.S.A. from sustainable native North American solid cherry, maple or black walnut.
