When you go to arrange a tune, such as a standard, chances are that you will need to add some harmonic interest by inserting some well chosen alternate changes. When doing so, it is important to have a firm grounding in how roots of chords move from one chord to the next.
This lesson covers the four main ways that chords move. Become familiar with these and always keep them in mind when figuring out logical and nice sounding alternate changes to a tune. As always, questions and comments are welcome.
