Analysis
The key pair is D major and its relative B minor (2 sharps). 4 different chords appear 68 times in total; 3 of them sit naturally inside the shared scale. E acts as a secondary dominant, briefly pointing at another chord of the key.
Chord movement
- G A DIV → VIV → V BmVI → VIIVI → VII ×1
The move to watch is G → A, heard once. From the D side it reads IV → V (IV → V: the lift that builds tension before home); from the Bm side it is VI → VII (VI → VII: the rising step that heads for the tonic). Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.
Improvisation tips
- D major pentatonic and B minor pentatonic are the same five notes (D – E – F# – A – B): start from D for a brighter phrase, from B for a bluesier one.
- Over A, land on A, C#, E — the chord's own tones always sound right on strong beats.
- Over E, land on E, G#, B — the chord's own tones always sound right on strong beats.
- Over A6, land on A, C#, E — the chord's own tones always sound right on strong beats.

The song's harmonic story
The opening E lays a solid floor for everything that follows. The backbone is A, E, A6, G — V–V/V–V6–IV from the D side, VII–IV–VII6–VI from the Bm side. E adds a moment of surprise: secondary dominant V/V — leads to A. Keep an ear on G → A (IV → V in D, VI → VII in Bm): IV → V — the lift that builds tension before home. Ending on A, the song seals D 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.
