Degree-by-Degree Analysis

The iii chord (B unknown) functions as a substitute for the I or vi. The IV chord (D minor seventh) is the subdominant — it adds motion and moderate tension. The V chord (D# minor seventh) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (D diminished) is the relative minor — it brings emotional color and depth. The vii° chord (D# minor) is the diminished — the most tense, rarely used alone, usually leading to the I.
