Watch the Mirror Mirror online guitar lesson by Brad Carlton from Chord Studies: Pedal Tones Vol. 1
This example continues the idea of the previous one, but now we're going to be moving up the neck. Our first Dm shape is coming right out of your Dm barre chord, and of course we make that one note move from A to B♭ for our IV chord. The last half of the progression mirrors the moves done in example 11, but up an octave. Usually a pedal tone is kept static and doesn't shift the octave, but in this case we are popping up to the 12th fret D for a difference in sound. You should also try playing these shapes with the open D string to get the more traditional pedal tone sound.
