Degree-by-Degree Analysis
The I chord (GMaj7) is the tonic — the gravitational center of the key. The ii chord (Am7) is the minor subdominant, commonly used to approach the V chord. The iii chord (Bm7) functions as a substitute for the I or vi. The IV chord (CMaj7) is the subdominant — it adds motion and moderate tension. The V chord (D7) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (Em7) is the relative minor — it brings emotional color and depth. The vii° chord (F#m7b5) is the diminished — the most tense, rarely used alone, usually leading to the I.
