A musical score display apparatus installed in an electronic musical instrument such as a player piano is designed to automatically display and change over images of electronic musical score data on the screen. A user's voice (or vocalization) is input by means of a microphone and an A/D converter, so that the input voice is subjected to signal processing to produce voice data. The voice data is then subjected to voice analysis such as phoneme analysis to determine an arrangement of phonemes that are included in the input voice and that highly matches one of prescribed words listed in advance in a word dictionary. Recognition data is created based on the arrangement of the phonemes and is subjected to command interpretation with reference to prescribed commands that are listed in advance in a command database. For example, the command database registers a command "NEXT' for designating the next page of the musical score to be displayed on the screen and a command "BACK' for designating the previous page of the musical score to be displayed on the screen. Herein, one of the commands that highly matches the recognition data is chosen and is used to control images of the musical score being displayed on the screen. In addition, it is possible to detect a tone volume or a tempo from the input voice. Thus, musical performance is automatically controlled based on the electronic musical score data in response to the detected tone volume or tempo.
