Provided is a method for generating a song melody. The method includes: displaying a melody configuration page; acquiring melody attribute information selected based on the melody configuration page; displaying a melody generation button in a triggerable state on the melody configuration page in response to selection of the melody attribute information being completed; displaying a candidate melody page in response to a triggering operation on the melody generation button; and determining one or more selected candidate melodies from at least one candidate melody as a target melody.

Systems, devices, and methods for encoding the harmonic structure of a musical composition in a digital data structure are described. Tonal and rhythmic commonalities are identified across the musical bars that make up a musical composition. Individual bars of the musical composition are each analyzed to characterize their respective harmonic fingerprints in various forms, and the respective harmonic fingerprints are compared to sort the musical bars into harmonic equivalence categories. Isomorphic mappings between hierarchical data structures that encode the musical composition based on musicality and harmony, respectively, are also described. The systems, devices, and methods for encoding the harmonic structure of a musical composition in a digital data structure have broad applicability in computer-based composition and variation of music.

According to an embodiment, there is provided a system and method for automatic AI-based song construction based on ideas of a user. In some embodiments, an embodiment is provided with a database that contains harmony templates which can be used by the user to augment the playback of a given music work. Various embodiments of the instant invention also benefit from a combination of expert knowledge resident in an expert engine which contains rules for musically correct song generation and machine learning in an AI-based audio loop selection engine for the selection of compatible audio loops from a database of audio loops.

A system and methods for collaborating on a musical composition over a communication network, the system having processing circuitry that obtains the musical composition stored within a data storage device of the system, the musical composition including a first musical input data associated with a first channel, receives, via the communication network, second musical input data from a client device, the second musical input data being associated with a second channel, generates a data block based on the received second musical input data, the generated data block including synchronization data associated with the second musical input data relative to at least a portion of the musical composition, and transmits the data block to memory, the memory being accessible via the communication network to the client device and other client devices that are collaborating on the musical composition.

According to an embodiment, there is provided a system and method for automatic AI controlled loop based song construction. It provides and benefits from a machine learning AI in a audio loop selection engine for the generation of a song structure and for the selection of fitting audio loops from a database of audio loops. In one embodiment, the instant method provides a music generation process that utilizes an AI system that has been trained and validated on a music item database to complete the creation of a music item given an incomplete song that was started but not finished by a user.

The information processing device 100 provides an interface capable of generating music information by editing a part of elements forming the music information, and generates new music information by a machine learning model on the basis of a plurality of pieces of music information created using the interface.

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.

A computer system for enabling generation/controlling/modification of sound elements is provided. A computer program defines a sound engine. The sound engine includes or is linked to one or more musical composition interfaces that enable one or more users to access a music generator/controller/modifier utility (“music generator”), so as to graphically map one or more musical notes by tracing one or more Bezier paths defined that are processable by the music generator so as to define five fundamental note qualities: Tone, pitch, volume, applied effects and duration. The music generator enables user manipulation of the Bezier paths, including touch input modification of the paths (e.g. dragging, forming etc.) that modify fundamental qualities of the corresponding note.

A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

The invention relates to a user interface for a musical instrument, in particular an electronic or virtual musical instrument, for playing combined sequences of chords and tunes, comprising a key matrix (1) having a plurality of zones 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . that can be activated, these zones being arranged in columns and rows, each row of activatable zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . forming a region 101, 102, . . . , each region 101, 102, . . . being associated with a basic chord that preferably is a chord of a scale, preferably of a diatonic scale, the chord being specific of the scale, and each zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . being associated with a musical tone of the tune, which is preferably a musical tone of the tune of the scale. The user interface is designed to produce, when a zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . in a region 101, 102, . . . is activated, a musical tone-producing command in accordance with the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . and region 101, 102, . . . , and the musical tone-producing command comprises at least one basic chord note command of a pitch that is contained in the basic chord associated with the activated region 101, 102, . . . and comprises a tune note command the pitch of which corresponds to the musical tone of the tune of the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . . The invention also relates to a musical instrument, a method for producing combined sequences of chords and tunes, and a computer-readable storage medium.
