ABSTRACT:
An electronic musical instrument generates musical tones corresponding to a melody tone and a chord tone which are designated by a performer. In order to apply a specific musical effect or generate an ornament, a front percussive tone, or forefall, is automatically added to the melody tone, wherein this front percussive tone has the predetermined pitch difference with respect to the melody tone. This front percussive tone is additionally generated prior to the melody tone in the predetermined short period. Instead of this front percussive tone, it is possible to generate an additional tone which has the same tone name as any one of constituent tones within the chord tone but its tone pitch is different from that of the melody tone. When generating plural melody tones and plural additional tones, these tones are sequentially generated by a predetermined time difference in a pitch descending or ascending order.
