Watch the Gate's Girl online guitar lesson by Corey Congilio from Essentials: Texas Blues Solos
First, I want you to notice the chord changes. This is a normal 12 bar form, but bars 11 and 12 contain the I-IV-II-V chord progression. This style of turnaround is very common in jazz and swing tunes like this one. The melody contains some great "licks" on it's own. The solo employs some typical jazz blues phrasing, but you'll notice how many of those phrases start on upbeats. I'll explain this more in the video, but starting phrases on upbeats is a great way to jazz up your solos. From a technique standpoint, this solo isn't very difficult. The key is playing "behind the beat" at some points and to really stay loose throughout the entire piece.
