A generative composition system reduces existing musical artefacts to constituent elements termed “Form Atoms”. These Form Atoms may each be of varying length and have musical properties and associations that link together through Markov chains. To provide myriad new composition, a set of heuristics ensures that musical textures between concatenated musical sections follow a supplied and defined briefing narrative for the new composition whilst contiguous concatenated Form Atoms are also automatically selected to see that similarities in respective and identified attributes of musical textures for those musical sections are maintained to support maintenance of musical form. Independent aspects of the disclosure further ensure that, within the composition work, such as a media product or a real-time audio stream, chord spacing determination and control are practiced to maintain musical sense in the new composition. Further, a structuring of primitive heuristics operates to maintain pitch and permit key transformation. The system and its functionality provides signal analysis and music generation through allowing emotional connotations to be specified and reproduced from cross-referenced Form-Atoms.

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.

An apparatus, method, and computer-readable storage medium that generate a harmonized musical piece. The method includes receiving a chord selection including a musical key and a scale selection, generating, within a digital audio work session, a chord progression sequence based on the received chord selection, in response to a detected chord selection change, modifying the chord progression sequence to include a chord progression corresponding to the chord selection change, setting the chord progression sequence as a master sequence, in response to detecting a second progression sequence within the digital audio work session, transmitting an identifier to the second progression sequence setting it as a slave sequence, and establishing a synchronized communication link between the master and the slave sequences such that changes made in the master sequence are automatically effectuated in the slave sequence, and combining the master sequence and the slave sequence to form a composed musical piece.

The embodiment relates to systems and methods structured to deliver acoustic and visual energies to be received by living beings, and, more particularly the energies received by living beings can be configured, composed, and/or designed to be delivered to address a plurality of conditions including enjoyment. The energies can be deployed by using various algorithms and can include tones, tuning, rhythms, sound waves, harmonies, melodies, chord progression and instrument arrangement to deliver the energies preferentially to different parts of a living being's body, such as but not limited to, right and/or left ears. The algorithms can include variations in Pythagorean tuning and just and pure intonation, monaural and binaural beats for brain wave entrainment, Solfeggio Frequencies, Fibonacci Sequencing, and/or carrier waves and isochronic tones.

Techniques are provided for generating an output file. One technique involves the steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; generating a harmonic chord map for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and generating the output file by combining the selected subset of content blocks and the input file. This technique may enable the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.

Computer-based systems, devices, and methods for automatically generating aesthetic chord progressions and key modulations in musical compositions are described. Known harmonic relationships are expanded upon to produce a much richer set of harmonic transition probability models compared to conventional music theory, and these models are leveraged by a computer-based musical composition system to generate new musical compositions and variations of existing musical compositions. Techniques for enabling a computer-based musical composition system to automatically determine when to introduce a key modulation, what key to module to, and what chord progression(s) to use within the new key are all described.

Described herein are techniques for adjusting notes of a first musical piece based on chord data of a second musical piece. A first musical piece is accessed, wherein the first musical piece comprises a plurality of notes. Chord data associated with a second musical piece is accessed. One or more of the plurality of notes are compared to the chord data. An aspect of the one or more of the plurality of notes is changed based on the comparison.

A processor-based method of producing a generative musical composition is disclosed herein. The method includes the step of receiving a briefing narrative which describes a musical journey by referencing a plurality of emotional descriptions related to a plurality of musical sections. The generative musical composition is assembled with regard to the briefing narrative through the selection and concatenation of Form Atoms with tags that align with the emotional descriptions related to the musical sections. The Form Atoms, which have compositional nature aligned with the emotional descriptions and self-contained constructional properties representative of the historical corpus of music, are then selected and substituted into the generative composition. The method further involves the step of generating the musical composition by mapping musical transition between selectively chosen Form Atoms to reflect pre-established transitions between Form Atoms and groups Form Atoms that have been identified to have similar tags but different constructional properties.
