Abstract: A generative composition system reduces existing musical artefacts to constituent elements termed “Form Atoms”. To provide myriad new composition, a set of heuristics ensure 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 practiced to maintain musical sense in the new composition. Further, a structuring of primitive heuristics operates to maintain pitch and permit key transformation.

Abstract: The disclosed generative composition system produces a composition to a briefing that describes a musical journey in emotional descriptions. The composition is assembled from concatenated interchangeable Form Atoms “FAs” selectable by tags aligning emotional descriptions with respective compositional heuristics. Each FA has self-contained constructional properties representative of an historical musical corpus. These heuristics support generation of chords, in chord schemes of musical tonics, achieving an equivalent form function. Each FA also includes chord spacer heuristics that temporally space generated chords across a defined musical window, and a chord list in a local tonic defining branching structures giving options for generating different chords. A progression descriptor, in combination with a form function, expresses musically a question, an answer or a statement, with each FA creating a meta-map of a chord scheme for a musical section.

The generated frequency signal is then played back after processing.
