A method generates a sound signal in accordance with score data representative of respective durations of a plurality of notes and a shortening indication to shorten a duration of a specific note. The method includes generating a shortening rate, generating a series of control data, and generating a sound signal. The shortening rate is representative of an amount of shortening of the duration of the specific note, and is generated, by inputting, to a first estimation model, condition data representative of a sounding condition specified by score data for the specific note. Each of the series of control data is representative of a control condition of the sound signal corresponding to the score data, and the series of control data reflects a shortened duration of the specific note shortened in accordance with the generated shortening rate. The sound signal is generated in accordance with the series of control data.

The invention generates progressive music in real-time for video games using random, seeded random, and manually input variables to affect melody, phrase length, harmonic chords and complexity, and percussive accompaniment. As the game is played, variables may be passed in that change the music to increase or decrease complexity and tension levels and to interpolate between styles. The generated music then progresses from stable, simple, and consonant to more tense, dissonant, and complex melodies, harmonies and rhythms, and back to the original stage as a musical resolution. Through variables controlling musical parameters, music may progressively change from the atonal region where there is no clear resolution or stability, to tonal, where there is only consonance and stability, and anywhere in between. These variables are assigned through a middleware or a game-engine setup that uses the current device as an audio source plugin, or manually coded into the individual video game.

A signal generation method implemented by a computer system includes: generating an audio signal in response to a manipulation of each of a first key and a second key; and controlling generation of the audio signal based on a reference point that is a position of the first key at a time point of a manipulation of the second key, based on the second key being manipulated during a manipulation of the first key.

One or more assigners selecting a note to be sounded according to operation state of plural controls corresponding respectively to notes are provided, it is decided for each of the assigners whether or not to select a note to be sounded in response to a key-off operation of any of the controls, and when a key-off operation of any of the controls is detected, the assigner which is decided to select a note to be sounded, is instructed to select a note to be sounded according to operation state of the controls after the detection of the key-off operation.

A method performed by one or more processors in an information processing device for an electronic musical instrument includes, via the one or more processors: receiving performance data generated by a user performance of the electronic musical instrument; extracting time-series characteristics of a sequence of notes from the performance data; detecting a performance technique from the extracted characteristics; and generating an image data reflecting the detected performance technique and outputting the generated image data.

An electronic musical instrument includes a performance operator and at least one processor. In accordance with pitch data associated with the performance operator operated by a user, the at least one processor digitally synthesizes and outputs inferential musical sound data including inferential performance technique of a player. The inferential performance technique of the player is based on acoustic feature data output by a trained acoustic model obtained by performing machine learning on: a training score data set including training pitch data; and a training performance data set obtained by the player playing a musical instrument and is not played in the user operation of the performance operator.

A method for electronic music generation comprising electronically applying one or more functions that change one or more compositional elements of a musical input in a first tonality or other musical representation to generate a musical output in a second tonality or other musical representation and recording data corresponding to the musical output in a recording medium or rendering such musical Transformations to a reproductive medium such as an amplifier and speakers or headphones.

A method includes displaying, by an electronic device, a first interface, where the first interface includes a recording button used to record a first song, obtaining, by the electronic device, accompaniment of the first song and feature information of a cappella of an original singer, starting to record a cappella of the user that is sung by the user, and displaying, by the electronic device, guidance information on a second interface based on the feature information of the a cappella of the original singer, where the guidance information guides one or more of breathing and vibrato during the user's singing.

An electronic wind instrument includes a tonguing sensor which detects tonguing, a breath sensor which detects a breath value, a loudspeaker which outputs a musical sound and a processor which controls the musical sound, in which the processor acquires a tonguing value which depends on a tonguing time which is the time which has elapsed after start of the tonguing which is detected by the tongue sensor, decides a silencing effect value which indicates a degree of volume reduction depending on the tonguing value, acquires the breath value which depends on a magnitude of a breath sensor signal which indicates a result of detection by the breath sensor and makes the loudspeaker emit the musical sound whose volume which depends on the breath value is reduced depending on the silencing effect value.

Disclosed is a computer-implemented method and system for generating musical notations for a musical score. The method comprises receiving, via a first user interface, a musical note event of the musical score, processing, via a processing arrangement, the received musical note event of the musical score to determine one or more relevant music profile definitions therefor, defining, via the processing arrangement, one or more parameters to be associated with the received musical note event of the musical score based, at least in part, on the determined one or more relevant music profile definitions therefor and generating, via the processing arrangement, at least one notation output for the received musical note event of the musical score based on the defined one or more parameters associated therewith.
