Chord degrees: major and relative minor

Show the degrees above the chords — relative to Db or to Bbm; 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 Db major and its relative Bb minor (5 flats). 20 different chords appear 56 times in total; 9 of them sit naturally inside the shared scale. Bb7, Eb, Db7, Ebmaj7, Eb7sus4, C7 act as secondary dominants, briefly pointing at another chord of the key. Gbm7, B7 are borrowed from the parallel minor, adding a darker shade to the major side.

The move to watch is Ebm7 → Ab, heard 3 times. From the Db side it reads ii7 → V (ii → V: the classic preparation of the dominant); from the Bbm side it is iv7 → VII. Knowing where these arrivals fall helps you feel the phrasing and anticipate the next chord.

The song's harmonic story

Starting on Db, the song gives away its key from the very first bar. The backbone is Db, Ebm7, Fm7, Bb7 — I–ii7–iii7–V7/ii from the Db side, III–iv7–v7–V7/iv from the Bbm side. Bb7 adds a moment of surprise: secondary dominant V/ii — leads to Ebm. Keep an ear on Ebm7 → Ab (ii7 → V in Db, iv7 → VII in Bbm): ii → V — the classic preparation of the dominant. Ending on C7, the song seals Db as home.
