Prompt
Act as a harmony teacher and composer. I want chord progressions that convey a specific mood, and I want to understand why they work.
Context:
- Mood or feeling: {{mood}}
- Genre or style: {{genre}}
- Instrument: {{instrument}}
- My level: {{level}}
- Preferred key: {{key}} (if I write “suggest one”, pick a key that is comfortable on the instrument)
Deliverables:
1. Four progressions of 4 to 8 bars. For each: Roman numerals, the chords in the key, and one sentence on the feeling it creates.
2. A short theory explanation: which device creates the mood (mode, borrowed chord, secondary dominant, pedal tone, deceptive cadence…).
3. How to play them on {{instrument}}: simple shapes or inversions for my level, and how to connect the chords with minimal movement.
4. A rhythm or strumming pattern suited to the style, written clearly (e.g., down-down-up).
5. A richer variation of the strongest progression (sevenths, sus chords, a borrowed chord) and when to use it, for example in the chorus.
6. Melody tips: which chord tones to emphasize over each chord.
Constraints:
- Do not claim a progression “is the one from” a specific song: I do not need it and it may be inaccurate.
- Check that every chord belongs to the key, or explain why one does not.
- If you are missing information to choose well, ask me first.
Format: a table for the progressions and numbered sections for everything else.How to use it
- Describe the mood with nuance (not just “sad” but “quiet Sunday melancholy”).
- Enter your instrument and level so you get shapes you can actually play.
- Loop all four progressions and keep the one that fits your melody or lyrics best.
- Then ask for a contrasting section (bridge) based on the one you picked.
Usage example
Mood: hopeful nostalgia · Genre: acoustic pop · Instrument: guitar · Level: intermediate · Key: suggest one.
Sample output
Suggested key: G major, comfortable on guitar with open chords and warm-sounding open strings.
1. Progressions
| # | Numerals | Chords | Feeling |
|---|---|---|---|
| 1 | I–V–vi–IV | G–D–Em–C | bright, with a wistful touch on the Em |
| 2 | vi–IV–I–V | Em–C–G–D | starts in memory and opens toward hope |
| 3 | I–iii–IV–iv | G–Bm–C–Cm | the borrowed Cm gives the nostalgic ache |
| 4 | I–II–IV–I | G–A–C–G | the A major (secondary dominant) lifts the mood |
2. Why it works
The borrowed minor iv (Cm) from the parallel minor brings in an E♭ that sounds like "what used to be," and returning to G resolves toward hope. Cm and A are not in G major: one is modal borrowing, the other a secondary dominant (V/V).
3. On guitar
Keep fingers 3 and 4 anchored on the 2nd and 1st strings, 3rd fret, through G, Cadd9 and Dsus4: your hand barely moves.
4. Strumming
Down-down-up-up-down-up, with a light accent on beats 2 and 4.
5. Richer variation (for the chorus)
Gmaj7 – Bm7 – Cadd9 – Cm6
6. Melody tips
Over Cm, lean on the E♭: that's the note that carries the nostalgia…

Frequently asked questions
What do Roman numerals mean in a progression?
They show which scale degree each chord is built on (I, IV, V, vi…). They let you transpose the progression to any key without changing its effect.
What is a borrowed chord?
A chord taken from the parallel key, such as a minor iv inside a major key. It adds a bittersweet color that works well for nostalgia or restrained emotion.
Can I ask for ukulele or piano?
Yes. Change the instrument and the prompt adapts the shapes: fret fingerings for ukulele, or left- and right-hand inversions for piano.
