Harmonic Analysis

This progression moves through G (Tonic) → C (Subdominant) → D (Dominant) → Bm (Mediant) → Em (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.
