Degree-by-Degree Analysis
The I chord (A#m7b5) is the tonic — the gravitational center of the key. The ii chord (BMaj7) is the minor subdominant, commonly used to approach the V chord. The iii chord (C#m7) functions as a substitute for the I or vi. The IV chord (D#m7) is the subdominant — it adds motion and moderate tension. The V chord (EMaj7) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (F#7) is the relative minor — it brings emotional color and depth. The vii° chord (G#m7) is the diminished — the most tense, rarely used alone, usually leading to the I.
