PURPOSE:To obtain the musical instrument which eliminates operation for tonality specification by detecting tonality from plural pitches which are specified for sound generation and performing pitch correction. CONSTITUTION:The tonality of performance is decided according to the pitches which are specified by a pitch specifying means and the frequencies of respective musical sounds are corrected into the frequency of a specific rhythm with the decided tonality. High frequency parts of respective musical sounds are generated at the corrected frequency. Consequently, the musical sound can be generated with the rhythm with the tonality without specifying a tone previously. For example, a ROM 12, a RAM 13, a keyboard 14, a switch group 15, a tone generator 16, and a clock generator 17 are connected to a CPU 10 which controls the whole operation through a bus 11. The ROM 12 is stored with an operation program, timbre data, etc., and registers stored with data, etc., regarding key events are set in the RAM. The tone generator 16 can generates plural musical sounds at the same time and when plural keys of the keyboard 14 are turned on at the same time, the musical sounds corresponding to the keys can be generated at the same time. |
