[1] The wind machine is constructed of a large cylinder made up of several wooden slats which measures approximately 75–80 cm (30–31 in) in diameter.The cylinder body of the instrument rests upon a stand and is typically covered with silk, canvas, or other material which is in a fixed position.[2] Another method of construction implements an electric fan, which is fitted with lengths of cane, rather than blades.[3] The wind machine is played by rotating the crank handle, which is attached to the cylinder, to create friction between the wooden slats and the material covering that touches the cylinder but does not rotate as the crank handle is turned.The sound of the wind machine can also be controlled by the tightness of the fabric covering the cylinder.
