Degree-by-Degree Analysis
The I chord (D (1-2-♭5)) is the tonic — the gravitational center of the key. The ii chord (Eb (1-3-♭5)) is the minor subdominant, commonly used to approach the V chord. The iii chord (E (1-3-♭5)) functions as a substitute for the I or vi. The IV chord (G (1-2-♭5)) is the subdominant — it adds motion and moderate tension. The V chord (G# (1-2-♭5)) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (A (1-3-♭5)) is the relative minor — it brings emotional color and depth. The vii° chord (Bb (1-3-♭5)) is the diminished — the most tense, rarely used alone, usually leading to the I.
