| description | Use when the user wants to generate, voice, or modify chord progressions. Examples - "give me a sad chord progression in C minor", "voice these chords for piano", "what's a good progression for cinematic music?", "extend this progression with more color tones". |
Generate or refine chord progressions with proper voicing. Music-theory grounded — no random Reddit-tier chord stacks.
Required: key + mode, mood/genre, target instrument. Optional: length (default 4 chords), tempo (for rhythmic feel).
If two are missing, ask in one sentence:
"What key and what mood?"
| Mood/Genre | Reliable progressions (in C / Cm) |
|---|---|
| Sad / cinematic | Cm – Ab – Eb – Bb (i-VI-III-VII), or Cm – Gm/Bb – Ab – Eb |
| Hopeful / pop | C – G – Am – F (I-V-vi-IV), or C – Am – F – G |
| Tension | Cm – F – Cm – G7 (i-iv-i-V), or Cm – Bb – Ab – G |
| Neo-soul / R&B | Cmaj7 – Em7 – Am7 – Dm7 (I7-iii7-vi7-ii7), or use modal interchange |
| Lo-fi / chill | Cmaj7 – Fmaj7 – Bb7 – Eb7 (mixolydian feel), or use ii-V-I in jazz extensions |
| Cinematic build | Cm – Ab – Fm – G (Aeolian + V) |
| EDM uplifting | Am – F – C – G (vi-IV-I-V — the "Axis") |
| Modal/dorian | Cm – F – Gm – Cm (i-IV-v-i in dorian) |
For each chord, place voices according to instrument:
If user wants "more color":
When moving from one chord to the next, move each voice by the smallest interval possible:
Write the chords to the target track using add_notes_to_clip. Each chord gets one full bar by default (override if user specified rhythm).
User: "Sad progression in F minor for piano"
Output:
Apply with add_notes_to_clip. Length = 1 bar each, velocity 90 default.
Use when the user has recorded vocals and wants a processing chain set up. Examples - "set up my vocal chain", "process this vocal", "make the vocal sit in the mix", "give me a pop vocal chain", "make this rap vocal aggressive".
Use when the user is unsure about tempo, time signature, or rhythmic feel choices. Examples - "what tempo should this be?", "should I switch to 3/4?", "is 95 BPM right for lo-fi?", "how do I make this feel less stiff rhythmically?".
Use when the user wants to set up sidechain compression - typically kick → bass, kick → pads, vocals → music bed. Examples - "sidechain my bass to the kick", "make the synths duck under the vocal", "add pumping to the chords".
Use when the user wants drum patterns by genre - kick, snare, hi-hat, percussion. Examples - "give me a trap beat", "house drum pattern", "DnB drums at 174", "lo-fi drums with swing", "boom-bap pattern".
Use when the user is finishing a track and wants to check it's ready to send to a mastering engineer or for self-mastering. Audits headroom, peak levels, mono compatibility, frequency balance, LUFS. Examples - "is this ready to master?", "audit my mix before export", "check my levels".
Use when the user references another track they want to emulate the vibe/sound of. Examples - "make this sound like Ólafur Arnalds", "I want a Tame Impala vibe", "match the mix of Kendrick's Money Trees". Translates artist/track references into actionable production decisions.
