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.

An electronic musical instrument includes an operation unit that receives a user performance; and at least one processor. wherein the at least one processor performs the following: in accordance with a user operation specifying a chord on the operation unit, obtaining lyric data of a lyric and obtaining a plurality of pieces of waveform data respectively corresponding to a plurality of pitches indicated by the specified chord; inputting the obtained lyric data to a trained model that has been trained and learned singing voices of a singer so as to cause the trained model to output acoustic feature data in response thereto; synthesizing each of the plurality of pieces of waveform data with the acoustic feature data so as to generate a plurality of pieces of synthesized waveform data; and outputting a polyphonic synthesized singing voice based on the generated plurality of pieces of synthesized waveform data.

An electronic musical instrument includes: a memory that stores lyric data including lyrics for a plurality of timings, pitch data including pitches for said plurality of timings, and a trained model that has been trained and learned singing voice features of a singer; and at least one processor, wherein at each of said plurality of timings, the at least one processor: if the operation unit is not operated, obtains, from the trained model, a singing voice feature associated with a lyric indicated by the lyric data and a pitch indicated by the pitch data; if the operation unit is operated, obtains, from the trained model, a singing voice feature associated with the lyric indicated by the lyric data and a pitch indicated by the operation of the operation unit; and synthesizes and outputs singing voice data based on the obtained singing voice feature of the singer.

An electronic vibrato system for a stringed instrument comprises an actuator and microcontroller which are disposed within a chassis. The control arm moves the actuator from a resting position to non-resting, rotated positions. The system is below a face of a stringed instrument such that the system has a disposed fulcrum within the instrument. The rotated positions impart resistive forces on said actuator and imparting control signals. The microcontroller processes said control signal and modulates pitch.

An electric guitar includes a body, a neck, and a tremolo device. A tremolo cavity for accommodating a tremolo spring is formed on the back of the body. A metal cover is attached to the tremolo cavity so as to cover the tremolo spring from the outside. A magnetic force generating portion that generates a magnetic force for fixing the metal cover to the body is provided in the vicinity of the tremolo cavity.

A sound signal conversion device includes a supplier. The supplier supplies a periodic change to an input sound signal and outputs the sound signal to which the periodic change is supplied. The supplier includes a phase determiner that determines a phase at which the periodic change supplied to the sound signal starts based on initial phase information when receiving a start instruction for starting supply of the periodic change to the sound signal.

A 128-note MIDI-range monophonic musical keyboard instrument (100) includes an octave keypad (106) with eleven keys arranged in an analog clock face format for octave selection with the thumb of one hand, a pitch keypad (108) with twelve pitch keys similarly disposed in a clockface arrangement around a central omnivalent thirteenth key (128), enabling the nondisjointed sounding of nonadjacent notes with the thumb of the other hand. Spatial manipulation of the device, such as tilting and jabbing, can switch octaves and activate other functions, enabling one-handed operation and overcoming small-screen space limitation. Aside from producing typical electronic piano or synthesizer sounds, the device can sing in human voice an extended monosyllabic solfege covering all twelve pitch families of the common chromatic 12-tone even-tempered scale. A pictograph-based music notation (156) mirrors the circular geometry of the pitch and octave keyboards and facilitates the intuitive reading and playing of a melody.
