This lesson takes our 12 bar blues to the next level by extending our chords as well as adding our Major 6th interval. The key is in B♭ Major which consists of the notes:
B♭ – C – D – E♭ – F – G – A
The chord progression is: I – IV – I – I – IV – IV – I – Vi – ii – V – I – Vi – ii – V – I
If you have some familiarity with 12 bar blues theory, then you may have noticed how the first half of the progression is a typical 12 bar blues progression, but the second half is not. The I – Vi – ii – V that is played twice at the end of this progression is a common jazz progression.
If your new to extended chords, this will require a lot of practice to sound smooth and timely, but it will be rewarding in advancing your chord changes, learning your Dominant chord shapes and improving upon your blues rhythm guitar playing overall.
Once you can play this progression smoothly, you can add some melodic lead lines in between the chord changes.
