An automatic accompaniment apparatus employs a chord designating section, a pattern memory, special operation designating section, a pattern read out section, a note conversion section and a tone generator. The chord designating section designates a root and a type of a chord. The pattern memory stores a performance pattern containing note data which designate tone pitches of musical tones. The pattern read out section sequentially reading out the note data from the pattern memory durring the automatic accompaniment. The note conversion section carrying out a note correction operation corresponding to the type designated by the chord designating section on the note data read out by the pattern read out section when the special operation is not designated. In contrast, the note conversion section outputs the note data read out from the pattern memory when the special operation is designated by the special operation designating section. The tone generator generates musical tone signals based on the note data outputted by the note conversion section. |
