Watch the Lookin' Sharp! Solo 1 online guitar lesson by Chris Buono from Guitar Lab: Blues Soloing
To clearly introduce playing over this new harmonic element the first chorus bends its way through the 12 bars with voice led chord tones. Kicking it off is a half step bend to the b7 (Bb) of the I chord (C7) followed by a shift of the fret hand up a half step only to bend a whole step to the 5th (C) of the IV chord (F7). In bars 5 and 6 you'll be using the 8th fret Eb as a launch pad first playing a whole step bend to the root of the F7 (F) and the pushing even further with a 1-1/2 step bend to F# to match the root of the F#dim7. When it comes to phrasing notice where you're playing on the downbeats and where you're anticipating chords by playing on the upbeat before they come in - another reoccurring idea you'll see throughout Blues Soloing.
