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