The keys slide under the strings, with the tangents set perpendicularly to the keys, reaching above the strings. Upon key-actuation, the tangent is pressed to meet the corresponding string, much like a fret, shortening its vibrating length to that point, changing the pitch of the string. It is primarily played underarm, suspended from the shoulder using a sling, with the bow in the overhanging arm.
