Minor view
A minor
Brightness rank 5/7 (leaning dark)
Characteristic notes
- b6 = F (the minor's melancholy)
- b7 = G (natural-minor colour)
Which side does the ear lean to?
Our reading: to us the song feels closer to the C major side because it both starts and finishes on C and C is heard 18 times against 9 for Am. That is an interpretation, not a rule — hearing the same chords from A minor is just as valid and teaches you something different.
Chord degrees: major and relative minor
Show the degrees above the chords — relative to C or to Am; comparing both readings is a practice of its own.
Every chord of the key, listed 1 to 7 separately for each key. Chords played in the song show how often they appear; chords from outside the scale sit next to their own degree.

Analysis
The key pair is C major and its relative A minor (no sharps or flats). 8 different chords appear 79 times in total; 6 of them sit naturally inside the shared scale. B7, A7 act as secondary dominants, briefly pointing at another chord of the key.
Chord movement
- F C CIV → Iplagal cadence AmVI → III ×9
- G C CV → Iauthentic cadence AmVII → III ×7
- B7 Em CV7/iii → iiisecondary resolution AmV7/v → v ×6
- G Am CV → videceptive cadence AmVII → iAeolian arrival ×5
- F G CIV → VIV → V AmVI → VIIVI → VII ×5
- Em Am Ciii → vi Amv → inatural-minor cadence ×4
The move to watch is F → C, heard 9 times. From the C side it reads IV → I (plagal cadence: the soft 'amen' ending); from the Am side it is VI → III. Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.
Improvisation tips
- C major pentatonic and A minor pentatonic are the same five notes (C – D – E – G – A): start from C for a brighter phrase, from A for a bluesier one.
- Over C, land on C, E, G — the chord's own tones always sound right on strong beats.
- Over G, land on G, B, D — the chord's own tones always sound right on strong beats.
- Over F, land on F, A, C — the chord's own tones always sound right on strong beats.

The song's harmonic story
The first chord is C; the ear learns where home is within a second. The backbone is C, G, F, Em — I–V–IV–iii from the C side, III–VII–VI–v from the Am side. B7 adds a moment of surprise: secondary dominant V/iii — leads to Em. Keep an ear on F → C (IV → I in C, VI → III in Am): plagal cadence — the soft 'amen' ending. Ending on C, the song seals C as home.
