Watch the Lookin' Sharp! online guitar lesson by Chris Buono from Guitar Lab: Blues Soloing
In this set of changes we have a "new" sound to solo over - the #ivdim7. This very cool passing chord makes for great lick-fodder and we'll be seeing it again and again throughout the course. When it comes to half step melodic voice leading, the #ivdim7 fits into the grand scheme of things quite nicely as you'll see in these next three solos.
