Watch the Teen Town Changes online guitar lesson by Teymur Phell from 30 Groove Master Bass Lines You MUST Know

Next I'd like to go over the chord changes for "Teen Town," which only has four chords. All four are 13 chords, meaning we have a 7 chord with a 13 added to it.

For example, a C7 chord consists of C the root, E the major third, G the fifth and Bb the minor seventh. On top of that we add an A note, which is the thirteenth degree, and so on with the other chords.
