mcp_opendaw_create_ambient_arrangement
Creates a 70 BPM ambient arrangement with sustained pads, drifting melody, minimal percussion, and sub-bass drone for atmospheric soundscapes.
Instructions
Create an ambient arrangement — 70 BPM atmospheric soundscape.
Ambient music (Brian Eno, Stars of the Lid, Aphex Twin Selected Ambient Works) focuses on atmosphere, texture, and sustained sound over rhythm and melody. Key characteristics:
60-80 BPM (or no clear pulse), 4/4 time
Long sustained pad notes with slow evolution
Sparse, minimal percussion (or none)
Drifting melodic fragments, no clear phrase structure
Reverb-drenched, wide stereo, cinematic
Modal harmony (sustained chords, slow changes)
Creates 4 tracks:
Pad (track_index): Long sustained chord notes (8 bars each), mode-based (major/minor/dorian/lydian), very slow harmonic rhythm. Root, fifth, octave — open voicings.
Melody (track_index+1): Sparse, drifting melodic fragments — long notes (2-4 bars), wide intervals, lots of space. Starts after 8 bars.
Drums (track_index+2): Extremely sparse — single kick on bar 1 of every 8 bars, occasional shaker. Almost subliminal pulse.
Bass (track_index+3): Sustained sub-bass drone, root note only, changes with pad harmony. Very low octave.
Default key: C major (most common ambient key). Default 32 bars for proper ambient evolution length.
