ABSTRACT:
An apparatus for adapting an electric player piano to play the hours, simulating the chimes of a clock, can be attached to the piano without alterations to the piano of a permanent nature. The apparatus includes a clock for actuating the piano on each hour and a switch responsive to actuation of a predetermined note by the piano for producing a control signal for turning the piano off. A second switch, responding to actuation of a second predetermined note, produces a signal for suppressing striking of the hour during the night. A sensor block carrying one or more switches may be placed upon the keyboard for detecting depression of corresponding keys. In addition, a key may be maintained in a partially depressed condition to prevent its sounding when it is used to produce a chime control signal.
