PURPOSE:To play respective chord kinds with invariably proper patterns by providing patterns correspondingly to chord groups and changing affiliated groups according to rhythm kinds. CONSTITUTION:Respective chord groups have patterns and which group a detectable chord is allowed to correspond to according to a rhythm is changed. Therefore, the best pattern among patterns prepared in the device, i.e., chord group is determined according to both the rhythm kind and chord kind. Consequently, it is checked which element [e.g. 7th system, M system, (m) system, etc.] of the specified chord is intense in consideration of the rhythm kind and even the same chord kind is put in a different group to obtain a more favorite pattern. |
