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