Samphor

[1][2] Depending on the ability of the musician, the samphor can make as many as 8 different pitches.

[1] The player of the sampho leads the pinpeat (a classical ensemble of wind and percussion instruments), setting the tempo and beat.

The samphor is made by hollowing out a single block of wood into a barrel shape.

[2] Both ends are covered with calfskin, tightened by strips of leather or rattan.

[1][2] The pitch to which the skin head is tuned becomes lower with a thicker layer of ash.
