About this course

Most musicians can play but cannot explain why a chord change pulls the way it does, how to transpose a song into a singable key, or what name to give the notes under their fingers. This course fixes that by building theory from the ground up: you start with the staff, the 12 pitches, and the formula for every interval, then construct major and minor scales, the circle of fifths, triads and seventh chords, and the functional roles (tonic, subdominant, dominant) that drive progressions in pop, jazz, classical, and film. You also master rhythm and meter and build a daily ear-training habit using named tools, so theory becomes something you can hear and use, not just diagram.
