Professional musician Julian Velard starts the course with the building blocks of harmony: notes, scales, intervals, chords, inversions, and basic chord progressions. He then goes into voice leading—showing how to move from one chord to another by changing just one or two notes—and reviews common song forms, from the familiar verse/chorus/verse of pop to the simple verse of the blues. At the end of each chapter, Julian explains the songwriting techniques shown in the chapter within the context of his own original commercially released songs.
