Abstract: An electronic musical instrument includes at least one processor that, in accordance with a user operation on an operation unit, obtains lyric data and waveform data corresponding to a first tone color; inputs the obtained lyric data to a trained model so as to cause the trained model to output acoustic feature data in response thereto; generates waveform data corresponding to a singing voice of a singer and corresponding to a second tone color that is different from the first tone color, based on the acoustic feature data outputted from the trained model and the obtained waveform data corresponding to the first tone color; and outputs a singing voice based on the generated waveform data corresponding to the second tone color.

Abstract: A keyboard musical instrument, a method, and a non-transitory computer-readable recording medium that improve operability are provided. An electronic musical instrument comprises a keyboard including plural white keys each of which is allocated with plural characters and plural black keys, and a controller. The controller executes, in a musical sound producing mode that is set, accepting a sound producing instruction of a musical sound in response to an operation of the keyboard, and, in a symbol input mode that is set, according to both a white key designated from the plural white keys and a black key designated from the plural black keys, accepting an input of a character among the plural characters allocated to the white key designated from the plural white keys.
