Watch the BBQ Boogie Solo online guitar lesson by Jeff McErlain from Essentials: Advanced Blues Soloing
Like many of the solos in this course, this one is a little tricky. I start off with a cool lick reminiscent of the opening lick to the solo in "La Grange", but I've extended the idea all the way down the A minor blues scale. Notice how it's a melodic pattern that repeats going through the scale. Melodic patterns are essential devices for any musician as they are an excellent way to move around the fingerboard musically . I personally love the sound of a pattern like this as it brings me through the scale as a listener.
It's important to swing those eighth notes and 16th notes in this solo, and almost every blues solo for that matter. The feel should be relaxed and a little behind the beat, which takes a fair amount of time to master. I know I'm still working on this all the time and it's the first thing to go If I haven't been practicing. Play the pattern slowly at first and hear the notes so you know exactly what the pattern is in your head. Slowly bring it up to tempo, that is the only way to get it.
