PROBLEM TO BE SOLVED: To prevent the disturbance of the performance of an electronic musical instrument which has to change the tonic of the key by operating buttons or the like when a tune other than the temperament is set. SOLUTION: An electronic musical instrument which can be tuned up to the tune other than the temperament consists of; a keyboard information output part which outputs the keyboard position information showing the position of the pushed key; a tune setting part which sets the tune; a waveform data memory part which stores multiple waveform data; a main control part which outputs the musical interval information and the waveform data selection information based on the keyboard position information; a waveform data output control part which outputs the waveform data whose musical interval is modified after reading the waveform data from the waveform data memory part based on the waveform data selection information and the musical interval information; a conversion part which converts the waveform data into sound and outputs them. The main control part decides the tonic of the tune which is set by the tune setting part based on the key position information when the chord is pushed, and the key, and outputs the musical interval information that modifies the musical interval of each sound in the chord into the musical interval that is decided by the tonic and the key. |
