Abstract
A keyboard musical instrument provides plural keys of a keyboard to be driven by an automatic playing system; although the automatic playing system selectively drives the keys in accordance with a performance rule expressing a music tune, a motion controller of the automatic playing system changes the performance rule if the human player drives the keys different from those defined in the performance rule so that the automatic playing system changes a part of the music tune in real time fashion during the automatic performance.
