Abstract
This invention provides players with easy identification of notes in a musical score and correspondences between performance operators and notes in a musical score. An electronic musical instrument comprises a keyboard having a plurality of keys, key-depression indicators each of which corresponds to each key, and a color monitor . A microcomputer embedded in the electronic musical instrument reads out performance data stored in memory such as RAM in sequence as time goes on, and lights the key-depression indicators to indicate keys to be depressed according to the performance data. The microcomputer also displays a musical score on the color monitor , using the performance data. Additionally, the microcomputer assigns a different color to each note name by using a note number in performance data, so that note colors used for the musical score display on the color monitor and light colors lighted by the key-depression indicators are controlled to correspond by note names.
