This site is based on independent research into chord progressions in tonal music and shows how chord progressions create musical phrase structures similar to sentence structures in natural language.

Students of music theory can use this site to understand the important role of chord progressions in tonal music. If this is your first visit, I suggest you view the Animated Demos first, followed by the Book Outline and then Example: How to harmonise a melody

Also included is a section on how harmony works in Pop and Rock Music

Analysts and researchers should also view the Thesis section which graphically illustrates the evidence for the theory. Please e-mail your thoughts. Press here for contact address.
