Watch the Double Up online guitar lesson by TrueFire from Play Blues Guitar 4: Rhythm Principles

Double Up - Overview is a video guitar lesson presented by Brad Carlton and is sourced from Chord Studies: Slow Blues Progressions Vol. 1.


This blues is in the key of A, but it's only four bars long. We'll repeat the form to make an 8 bar form. Take note of how the chord progression moves from A to C#7 to F#m as this is a slightly unusual change, but makes for some interesting rhythm guitar work.
