Which side does the ear lean to?
Our reading: to us the song feels closer to the E major side because E is heard 9 times while C#m never appears. That is an interpretation, not a rule — hearing the same chords from C# minor is just as valid and teaches you something different.
Show the degrees above the chords — relative to E or to C#m; 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 E major and its relative C# minor (4 sharps). 6 different chords appear 56 times in total; 1 of them sit naturally inside the shared scale. C, Am, F, G are borrowed from the parallel minor, adding a darker shade to the major side.
There's no textbook cadence here; the chords circle around each other in a loop, so the song feels more like a groove than a series of arrivals.
Empty slices are chords the song doesn't use.
The song is already written in its easiest key for guitar.
The first chord is C; the ear learns where home is within a second. The backbone is C, Am, F, E — bVI–iv–bII–I from the E side, #VII–vi–#III–III from the C#m side. C briefly darkens the picture: borrowed from the parallel minor. Ending on F, the song seals E 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.
