Machine Castanets for Hire
When used in an orchestral setting, castanets are sometimes attached to a handle, or mounted to a base to form a pair of machine castanets. This makes them easier to play, but also alters the sound, particularly for the machine castanets. It is possible to produce a roll on a pair of castanets in any of the three ways in which they are held. When held in the hand, they are bounced against the fingers and palm of the hand; on sticks, bouncing between fingers and the player's thigh is one accepted method. For a machine castanet, a less satisfactory roll is obtained by rapid alternation of the two castanets with the fingers.
