Abstract
In an automatic performing apparatus, an amount of change in a motion of a moving element provided in a baton is detected, and the detected change amount is converted into an electrical signal. A tempo clock signal generator provided in the apparatus is driven by the electrical signal to produce a tempo clock signal for reading out musical data preset in a memory. A volume level of a musical tone is set by a control section on the basis of the data of a peak level of the change amount in the motion of the baton. The tone data stored in the memory is read out on the basis of the tempo clock and is automatically sounded as a musical sound, at the set volume level.
