Watch the Pedal Pushin' online guitar lesson by Brad Carlton from Chord Studies: Pedal Tones Vol. 1

This pack of progressions involves pedal tones in the bass, meaning that the same note stays in the bass. Example 1 is a vi-IV progression in the key of C. Be careful on the first chord that you only strum through the third string. If you accidentally sound the second string, it'll give you an A major. Notice how A is our pedal tone here.
