Abstract: An electronic musical instrument includes: a memory that stores, before performance of a musical piece on the electronic musical instrument by a performer begins, pitch variation data that represents differences between fundamental tone frequencies of notes in a melody of the musical piece and fundamental tone frequencies of notes in prescribed singing voice waveform data; and a sound source that outputs a pitch-adjusted carrier signal to be received by a waveform synthesizing device that generates synthesized waveform data based on the pitch-adjusted carrier signal, the pitch-adjusted carrier signal being generated on the basis of the pitch variation data acquired from the memory and performance instruction pitch data that represent pitches specified by the performer during the performance of the musical piece on the electronic musical instrument, the pitch-adjusted carrier signal being generated even when the performer does not sing after performance of the musical piece begins.

Abstract: A piezo pickup which detects a key depression vibration occurred by a key depression operation is provided on the center of the lower surface of a key switch board where key switches of a keyboard are arranged. A CPU acquires the key number of a depressed key and a distance between the key switch of this key number and the piezo pickup in response to the key depression operation, and controls the sound volume and the tone color of a musical sound at a pitch corresponding to the key number based on control data acquired by correcting the detection output level (piezo input envelope waveform) of the piezo pickup in accordance with the acquired distance.

Abstract: An electric keyboard musical instrument 10 includes: keys 32; third switches 36 that detect that the keys 32 are pressed down to a position x3; various switches 12 to 15 that receive a selection of a kind of tone; and a CPU 21 that executes generating a sound with a tone of the kind received by various switches 12 to 15 in response to the third switch 36 detecting that a key 32 is pressed down to a position x3. The CPU 21 changes a time from when the third switch 36 detects that a key 32 is pressed down to position x3 until sound generation is executed, according to a kind of tone received through the various switches 12 to 15.
