ABSTRACT:
A device for guiding a player in his or her performance of a keyboard instrument is comprised of a movable indicator having a predetermined number of indicating or display elements registering with respective ones of the keys on the keyboard occasionally covered by the movable indicator. The shape of a predetermined number of musical notes are displayed on the indicating elements for sequentially specifying the keys to be acted upon during performance, the indicator being shifted in case of necessity to enable such sequential designation of the keys and to visualize the player's arm movement during performance. A plate may be optionally provided to have the chord part played automatically while the player is playing the melody part under instructions given by the movable indicator.
