摘要

A device (100) which can be used to control a musical performance contains a sensor which outputs an electrical signal. The sensor may be formed by providing a fixed contact (110) and a hollow contact (108), wherein movement of the device causes the contacts (108, 110) to meet. Other features of the device include a user-adjustable sensitivity feature, a button (104) for starting/stopping, and a sliding switch (102) for sending volume information to the playback devices. The device may be provided as part of a system which includes a score-following apparatus.
