Watch the Those Four Chords online guitar lesson by Angus Clark from 50 Radio Rock Licks You MUST Know

The chords in this progression are some of the most overused chords on Radio, particularly in the late 80's. In this context, we're borrowing the idea of an ostinato pattern from the classical world to create a riff that takes us through the whole progression. Use this idea as a jumping off point for creating your own riff ideas over tried and true progressions. 100s of great tunes can be written over the same four chords, it's all about how you connect them and what you do with them.
