Harmonic Analysis

This progression moves through B♭ (Tonic) → E♭ (Subdominant) → F (Dominant) → Dm (Mediant) → Gm (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.
