Watch the Careful: Ex. 2b online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 1: Johnny Winter
This excerpt picks up where the last leaves off, representing bars 7-12 of the 12-bar form and starting on the IV (four) chord, F. Over F, I play a repeated phrase based on C major pentatonic (C D E G A) built from an oblique bend, with the B string bent up one whole step while simultaneously fretting the high E string. I then move down to eighth position, and utilize G minor pentatonic (G Bb C D F) over the V (five) chord, G, shifting back to C minor pentatonic for the rest of the solo. Bar 11 features a very cool symmetrical riff played across the top two strings based on C Dorian (C D Eb F G A Bb).
