Watch the Careful: Ex. 2a online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 1: Johnny Winter
One of Johnny Winter's greatest studio recordings is the slow blues, "Be Careful with a Fool," from his first Columbia album, Johnny Winter, upon which this solo is based; this excerpt represents the first half, or six bars, of the 12-bar form. The most important thing about these lines, based primarily on C minor pentatonic (C Eb F G Bb) with occasional use of C major pentatonic (C D E G A), is that the phrases are very free, rhythmically speaking, as Johnny is known for cramming as many notes as possible into each beat of each bar.
