Harmonic Analysis

This progression moves through F♯ (Tonic) → B (Subdominant) → C♯ (Dominant) → A♯m (Mediant) → D♯m (Submediant).

A Classical-era progression that begins with a standard cadential setup but diverts through iii to vi, creating a deceptive resolution followed by a mediant color. This technique extends harmonic journeys in sonata and rondo forms.
