This skill should be used when the user asks to "analyze this progression", "analyze these chords", "what key is this in", "what function does this chord have", "analyze my song", "what's the Roman numeral for", "explain this chord sequence", "break down this progression", "harmonic analysis of", or provides a chord sequence like "C Am F G" for analysis. Returns songwriter-friendly analysis with chord roles, voice leading, and Nine Harmonic Cells classification. Theory terms provided optionally in [Theory] tags.

**Mode**: [major/minor/modal]
### Chord Breakdown
| Chord | Position | Role | Feel |
|-------|----------|------|------|
| C | 1 | Home | Stable, grounded |
| Am | 6m | Quiet home | Darker rest |
| F | 4 | Setup | Leaning toward something |
| G | 5 | Pull | Wants to go home |
[Theory: I (Tonic) → vi (Tonic) → IV (Pre-dominant) → V (Dominant)]
### The Flow
`Home → Home (darker) → Setup → Pull`
This is a classic building pattern: start grounded, add some shadow, lean forward, then pull hard toward resolution.
### Voice Leading (What Your Hands Do)
**C to Am**: Anchor fingers on C and E. Only G steps up to A.
*This is one of the smoothest moves possible — two notes stay put.*
**Am to F**: Anchor fingers on A and C. E slides up to F (half step).
*That tiny half-step creates forward motion.*
**F to G**: Everything moves. No anchors.
*This is the lift — all voices pushing toward the pull chord.*
### Cell Classification
**Cell**: Foundation (Grounding + Set Up)
This progression grounds the listener with home chords, then drives toward tension. Classic verse material.
### Similar Patterns
Found in corpus:
- **50s Progression** (1-6m-4-5): Exact match
- **Axis of Awesome** (1-5-6m-4): Same chords, rotated
### Why It Works
The 1-6m-4-5 progression is one of the most versatile in pop music. Every chord shares notes with its neighbors — C and Am share C and E, Am and F share A and C. This creates effortlessly smooth movement.
The final 5 chord (G) creates strong pull that wants to resolve back to 1, which is why this progression loops so well.
[Theory: The shared tones enable smooth voice leading, and the V-I tendency makes the progression feel complete when it cycles.]
When you find chords from outside the key:
Example:
"The Fm adds instant bittersweet quality — that melancholy tinge. [Theory: borrowed iv from parallel minor]"
Major chords where you'd expect minor (like E major in C):
Slash chords with bass moving by half-steps:
Analyze as verse/foundation progression in C major. Use: Home → Quiet home → Setup → Pull
This is a walk-down! Note the bass stepping: C → B → A → G → F Upper voices holding while bass walks down chromatically. Reference: This is the "Something" move.
