Abstract
An electronic musical instrument has a means used by a player to set a key name to which transposition is to be made and a part number to designate a transposition excluding part. Tone data in parts other than the transposition excluding part are exclusively subjected to transposition processing, and transposed tones are produced. For example, play data of a keyboard are set as a transposition excluding part, and their tones are produced in C major key as the key played. On the other hand, the keys of accompanying tones such as chord tones, rhythm tones, and the like programmed in keys other than C major key in a storage medium are transposed to C major key to produce transposed tones, allowing an ensemble play in common key.
