For the final four bars of Eric’s solo, he flits between several positions – this acts as a kind of consolidation to wind up his main solo over the chord turnaround. There are an awful lot of useful ideas concentrated into these four bars, so take the time to fully absorb them.
The last note of Eric’s solo leads to the beginning of BB’s. A favourite trick is to punctuate solos with a high exclamatory note (see bar 26 for the high B at the 19th fret). You’ll also hear phrases landing on the 6th (G#) – another BB trademark, though you’ll have noticed it in Eric’s playing too.
