Watch the Funky 12 Bar Variation 1 online guitar lesson by Corey Congilio from Rhythm Factory: Texas Blues
I like taking my students through different keys. We're in the key of F here and changing keys helps us see and hear things differently. Our chords throughout the progression are F7, Bb9, and C9. Pay attention to rests, and proper exectuion of the licks. You'll be getting funky like Freddie in no time!
