PURPOSE:To execute automatic accompaniment with high degree of freedom by reading data which is previously stored by means of the reference of a table from code type data, root sound data and reference musical interval data in previously generated accompaniment pattern data so as to obtain musical interval data of chord pronunciation. CONSTITUTION:A table reference means P2 obtains a differential value D6 which is previously stored as against subordinate sound which is to be generated based on reference musical interval data (note code D4) and code type data D5 in accompaniment pattern data (sequence data D1). A table reference means P5 obtains conversion musical interval data (conversion node code D9) which is previously stored based on reference musical interval data D4 and root sound data D7 in accompaniment pattern data D1. Then, the differential value D6 and conversion musical interval data D9 are added so as to obtain pronunciation data (output key number D8). |
