mcp_opendaw_create_chaconne
Compose a chaconne with repeating bass line, chord progression, and developing variations. Define bass notes, rhythms, chords, and choose from baroque, romantic, jazz, minimalist, or contemporary styles.
Instructions
Create a chaconne — repeating bass + chord progression + developing variations.
A chaconne is a set of variations over a repeating bass line and harmonic progression. Unlike ground bass (bass only) or passacaglia (bass + variations), a chaconne explicitly repeats both the bass AND the chord progression, building variations on top of this fixed harmonic framework.
Bass pattern: space-separated note names (e.g. "C2 G2 A2 E2"). Bass rhythm: space-separated durations in beats (e.g. "1 1 1 1"). Chord pattern: comma-separated chord names aligned with bass notes (e.g. "C,Em,Am,G"). Supports major, minor, dim, aug, maj7, m7, 7. Variation styles:
baroque: descending stepwise lines with suspensions, ornaments accumulate
romantic: wide intervals, expressive phrases, rubato-like timing
jazz: syncopated, chromatic passing tones, swing-like rhythm
minimalist: repeating cells with gradual phase shift
contemporary: dissonant clusters, intervallic leaps, pointillistic
Creates bass on track_index, chord pads on track_index+1, variation on track_index+2.
