mcp_opendaw_create_binary_form
Compose a binary form musical structure with A/B sections, optional repeats, and modulation choices, writing melody and bass to adjacent tracks.
Instructions
Create binary form — two contrasting sections (A|B) with optional repeats.
Binary form is the simplest structural form in Western music: two self-contained sections, each typically repeated. The A section establishes the tonic, the B section departs and returns. Found in Baroque dance suites (Bach, Handel), folk tunes, early jazz, and many pop structures.
Modulation types (how B section relates to A):
dominant: B section in the dominant key (V). Classical approach — Bach two-part inventions, Baroque dance movements.
relative: B section in the relative minor/major. Romantic and folk approach — gentler contrast.
subdominant: B section in the subdominant (IV). Church hymns, modal folk tunes.
parallel: B section stays in same key but uses contrasting melodic material. Minimalist/folk approach.
no_modulation: B section identical key, same harmonic center.
With repeat=True, each section is played twice (AABB structure), matching the traditional binary form with repeat marks.
A section: stepwise melody around tonic, I-V-I harmony. B section: contrasting melody in modulated key, wider intervals, returns to tonic at end.
Creates melody on track_index, bass on track_index+1.
