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