I know there's a decent amount of science that goes into creating a device that can set and maintain time, so this may be a very simple question with no"no" being the answer, but i'mI'm just curious wetherwhether there is any very early history of the pendulum or other autoautomatic timekeeping devices being used for musical purposes (accurately setting and maintaining tempo [bpm] and pulse).
