Which side does the ear lean to?
Our reading: to us the song feels closer to the C major side because it opens on C and C is heard 20 times against 8 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.
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.

The key pair is C major and its relative A minor (no sharps or flats). 12 different chords appear 90 times in total; 5 of them sit naturally inside the shared scale. Db, Bb, C#, Ab are borrowed from the parallel minor, adding a darker shade to the major side.
The move to watch is F → C, heard 8 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.
Empty slices are chords the song doesn't use.
The opening C lays a solid floor for everything that follows. The backbone is C, F, G, Db — I–IV–V–bII from the C side, III–VI–VII–#III from the Am side. Db briefly darkens the picture: neapolitan bii — a dark, dramatic colour a half step above the tonic. Keep an ear on F → C (IV → I in C, VI → III in Am): plagal cadence — the soft 'amen' ending. Ending on Ab, the song seals C as home.
This analysis is generated from the song's chords by akorculuk's harmony engine using consistent rules. When you change key, the degrees stay the same; only the chord names change.
