ABSTRACT:
Respecting plural accompaniment patterns belonging to a common accompaniment style, an order is predetermined in which accompaniment patterns are sequentially changed. For example, this order may be predetermined to be an order in which a change of the accompaniment patterns can accomplish a more natural change in an accompaniment tone. Data indicative of a performance state on a keyboard is compared with a predetermined reference value. Whenever a comparison condition is satisfied, change of the accompaniment patterns is effected in the predetermined order. Data related to a changed-over accompaniment pattern is read out from a memory, based on which data an automatic accompaniment tone is generated. There may be a plurality of the predetermined orders. One order may be such that the accompaniment patterns are changed to allow an automatic accompaniment tone to achieve a progressively flourishing mood and another order may be such that brings an effect opposite to that achieved by the one order. Selection may be automatically made of the orders on the basis of a changing trend of the keyboard performance state.
