Watch the Stretched on the Left online guitar lesson by Brad Carlton from Chord Studies: Slow Blues Progressions Vol. 1

This example is a slow blues in C minor. There are a lot of extended and jazz style chords in this one, so your left hand will get stretched and you'll really have to play close attention to the fingerings to be successful with this particular progression. Watch for places you can use your index finger of your left hand as a guide finger, sliding on the same string from one chord to the next.
