Claim 0:
1. A generative composition system, comprising:
an input coupled to receive a briefing narrative describing a musical journey with reference to a plurality of emotional descriptions for a plurality of musical sections along the musical journey;
a database comprising a multiplicity of Form Atoms having self-contained constructional properties representative of an historical corpus of music and where each Form Atom has:
a generative set of heuristics that support generation of a set of chords in a chord scheme or many different sets of chords in the same or different tonics that achieve an equivalent form function and which thus have similar associated emotional and musical connotations, and chord spacer heuristics that space out temporally any number of generated chords across a defined window of musical time;
a tag that describes compositional heuristics of its respective Form Atom;
a chord list in a local tonic where the chord list defines branching structures giving options for generation of different chords from the local tonic, and
a progression descriptor in combination with a form function that expresses musically one of a question, an answer and a statement, and

wherein:
each Form Atoms creates a meta-map of a chord scheme for a musical section; and

processing intelligence responsive to the briefing narrative and coupled to the database, wherein the processing intelligence is arranged to:
assemble a generative composition having regard to the briefing narrative through selection and concatenation of Form Atoms having tags that align with emotional descriptions timely required by respective ones of the plurality of musical sections; and
select and substitute Form Atoms into the generative composition, the substitute Form Atom obtained with reference to the historical corpus of music and having its compositional heuristics aligned with the emotional descriptions; and

wherein musical transitions between Form Atoms are mapped in the generative composition to reflect pre-established transitions between Form Atoms and such that groups exist in which Form Atoms are identified as having similar tags but different constructional properties.
