ABSTRACT:
An apparatus for visually displaying music notes on a note display panel mounted on an electronic piano with a support arm. The electronic piano has a keyboard electrically coupled to an electronic circuit operable to produce an audio output in accordance with the depression of one or more keys. The arm is rotatably in a mount attached to the piano for movement about a first upright axis. A first motion limiting unit attached to the mount and arm limits the rotation of the arm about the piano. A second motion limiting unit attached to the panel and arm limits rotation of the panel about an upright axis relative to the arm. A modified structure has the arm fixed to the piano. The panel has a grand staff indicia coordinated with vertically disposed first light means corresponding to chord note information and second light means diagonally corresponding to an ascending note scale information. A keyboard representation is located below the staff indicia. Third light means associated with the piano key indicia of the keyboard representation is coordinated with the second light means to provide visual information as to the keys depressed on the electronic piano. An electric circuit means having on-off switches electrically couples the electronic piano with the first, second, and third lights so that the lights can be selectively operated. The electronic circuit has a switch assembly having a plurality of key signature switches operable to coordinate the first, second, and third lights with the piano keyboard in accordance with the key signature of the music that is played.
