Based on independent research, this site shows how chord progressions create musical phrase structures in tonal (and tonally influenced) music similar to sentence structures in natural language. The site also explains voice leading and how voice leading interacts with chord progression patterns.

Students of music theory can use this site to understand how chord progressions work. 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. Referencing this website? press here for guidelines.
