Watch the Minor Soloing 9 online guitar lesson by Brad Carlton from Bluesology 2

Bar 4 can be a very "busy" measure from a harmonic standpoint. This concept of inserting more chords is applied throughout the 12 bar form in this lesson. This also presents a greater challenge for the soloist. Each revision is explained in-depth thus enabling you to have a "move" as a safety net so you don't "lose the changes" in your solo. Part 2 of this lesson introduces the IV7 chord and also gives you some more time on the V7/bII7 move.
