Watch the Connect: Single String online guitar lesson by Dave Celentano from CAGED Commander
A great way to start seeing how the patterns connect is to play the C major scale ascending and descending on a single string as in this example (see attached chart). Use your index finger to run up and down the major scale while calling out the numeric name for each note. Can you see the individual 'CAGED' patterns as the scale progresses through them? Do this on all six strings by finding the lowest 'C' note on each string, then play the major scale from that point.
