KEYING DISPLAY DEVICE, AND ELECTRONIC KEYBOARD MUSICAL INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To display keying in a wide range by a small keying display device.

SOLUTION: The narrow keying display device 1 is used for displaying the keying of a middle range in a keyboard 3. When a user practices a left hand at a low range, the keying display device 1 is moved to a first position at the left end. A position selecting switch 8b decides a pitch change amount corresponding to a movement amount per one octave in the display device 1. A playing information change part 24 shifts pitch information of playing information by the change amount corresponding to positions. An LED display data generating part 25 generates LED display data for energizing an LED display means in response to playing information which is changed in a pitch part. By the display data, keying is displayed in response to the pitch which is changed by one octave.
