Harmonic Analysis

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