ABSTRACT:
A programmable piano has a keyboard in which each of the keys has a transparent window and a rotatable roller is mounted beneath the keyboard such that the surface of the roller directly beneath each of the keys is visible through the transparent window thereof. A sheet of music is carried by the roller and has a progression of notes thereon which are representative of a musical composition. A motor drives the roller and thereby presents to the windows of the keys in proper order and at a regulated rate the progression of notes so that a person can play the musical composition by manipulation of the keys selectively in accordance with the notes which appear in the windows.
