Abstract
By a musical performance guide which is in 'waiting mode' with a 'tempo-follow' enabled setting, an electronic musical instrument illuminates a guide lamp at a point in time which is earlier by a tone-generation start allowable period Ta than the note-on timing of a musical tone of a melody part of automatic musical performance data to start musical performance guide. The tone-generation start allowable period Ta is an allowable time #which is sufficiently longer than that of a case of a tempo-follow disabled setting. When a user has depressed a correct key within the tone-generation start allowable period Ta, the electronic musical instrument starts generating a melody tone to move the position of the automatic musical performance data which is to be reproduced forward.
