摘要： [Problem] To provide an arpeggiator capable of creating a rich arpeggio performance that includes multiple pieces of performance information, and a program equipped with a function therefor. [Solution] When the key press mode for a sounding part is a chord, a synthesizer 1 acquires all note numbers from a remain table for the sounding part in a setting table 11e and stores all the note numbers in an Arp note memory 12b. This allows all the notes corresponding to the note numbers set in the remain table to be concurrently generated at the sounding time set in an Arp pattern. That is, an expressive arpeggio based on a chord made up of all the notes corresponding to the note numbers set in the remain table can be produced.

摘要： An information processing device (100) according to the present disclosure is an information processing device that controls a first application (20) and a second application (20) that functions as a plug-in that extends functions of the first application. The first application includes a control unit (161) that controls operation of the second application in the first application, and the second application includes a selection unit (166) that selects setting information for controlling a composition function based on machine learning, and a transmission/reception unit (167) that transmits the setting information to an external server (200) that executes a composition function based on machine learning and receives music data composed by the external server through a network.

摘要： A system and method for making musical decisions is provided. The approach is based on algorithms which compose music driven by an input of desired emotional tension over time. A method for abstraction and quantification of musical structures is detailed, as well as the application of this method in a generative algorithm that produces musical sequences. The overall goal of this method is to use a set of abstractions and guidelines to generate emotionally appropriate new music in real time.

摘要： The present invention provides method and system for composing music with chord accompaniment. One or more keys on a first keyboard are selected by end-users to generate a chord progression, and a computer generates a chord progression MIDI file, and associates the file with a first physical card that is embedded with a unique machine-readable ID (UID). After the UID of the first physical card is subsequently recognized, the chord progression MIDI file is retrieved and played. While the chord progression MIDI file is played, certain keys on a second keyboard are highlighted, and each of the highlighted keys on a second keyboard represents a music note that is in harmony with a particular chord in the chord progression while the particular chord is being played, and one or more of the highlighted keys on the second keyboard are selected by the end-user to compose a melody.

摘要： Method of teaching a vocal harmony involves a computing device which automatically generates a plurality of audio presentations of a musical composition in a predetermined series. Each audio presentation in the series is different from the other audio presentations in the series and is configured to assist the user in progressively learning the selected vocal harmony part. Each of the plurality of audio presentations in the predetermined series is made different from others of the audio presentation in the predetermined series by selectively controlling (1) the particular ones of the plurality of vocal harmony parts that are included in each of the audio presentations, and/or (2) a magnitude of an audio volume that is applied to each of the plurality of vocal harmony parts that is included in each of the audio presentations.

摘要： Performance information of one or more accompaniment parts is extracted from original performance information. Arranged accompaniment performance information is created using, in accordance with a predetermined arranging condition, only any one or more of pitch names included in the extracted accompaniment performance information. The predetermined arranging condition comprises instructing that any of chord component notes be thinned out in an identified chord progression, and arranged accompaniment performance information is created by thinning out an accompaniment note of a pitch name corresponding to the chord component note having been instructed to be thinned out. Another predetermined arranging condition comprises setting a ratio between chords and arpeggios in one or more measures, and a combination of chords and arpeggios in the extracted accompaniment part performance information is changed so that a ratio between chords and arpeggios in one or more measures in the extracted accompaniment performance information assumes the set ratio.

摘要： An accompaniment sound generating device includes a specifier, an accompaniment sound generator, and an accompaniment sound outputter. The specifier specifies a plurality of musical performance parts for which accompaniment sounds are generated based on an input musical performance sound. The accompaniment sound generator generates the accompaniment sounds that belong to the plurality of specified musical performance parts for each musical performance sound. The accompaniment sound outputter outputs the accompaniment sounds generated for the plurality of musical performance parts with timing for generating the accompaniment sounds aligned with timing for generating musical performance sounds.

摘要： A harmony generation device and a program for the same which can generate a natural harmony sound are provided. The harmony generation device (1) generates first and second harmony tones to which a voice input through a microphone (M) is shifted in pitch by first and second shift amounts calculated based on both the voice input through the microphone (M) and a chord determined from performance information of an electric guitar (G) input through an input device (34). That is, since the first and second harmony tones can be tones based on the chord of the electric guitar (G) that changes from moment to moment, the harmony sound obtained by mixing the first and second harmony tones with the voice input through the microphone (M) can be a natural harmony sound that is rich in variation according to the chord of the electric guitar (G).
