The circle of 4th progresses through all 12 keys, and in it lies the secret of chord progressions. You'll learn how to move from major 7ths to minor 7ths; from suspensions to resolutions; an you'll learn how easy it is to develop your improvisations simply by breaking up the notes of the chord progressions within the circle. A printed copy of the circle of 4ths is included with this course, naturally.
