Watch the A Form: Double Stop Exercise online guitar lesson by Dave Celentano from CAGED Commander

This double stop routine sits comfortably within the frame of the 'A form' scale pattern except the 7th fret/A string, which is relocated from the 2nd fret/D string. Play the two notes of the double stop with one swift down stroke or use 'hybrid picking' - pluck the lower note of the pair with a down pick stroke and the higher with the middle finger.
