Harmonic Flow as Directional Expectancy: Teaching Harmonic Motion in Contemporary Music

Harmony is often taught as a system of labels rather than as an experienced form of motion. In contemporary music education, this emphasis on symbolic identification can produce students who name chords accurately yet struggle to hear harmonic direction or momentum. This article proposes a pedagogical framework that reframes harmony as directional expectancy: a perceptual process shaped by voice-leading, contextual stability, and stylistic enculturation. Drawing on practice-led teaching, the framework introduces three topologies of harmonic motion—Steps, Spirals, and Fields—and a compact lexicon of momentum states. A genre-comparative analysis of the flat mediant (♭III) shows how chord quality encodes idiomatic flow across popular music, jazz, and musical theatre, foregrounding listening before analysis.
