Watch the Farther On Up: Ex. 5a online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 5: Eric Clapton
This excerpt, played over a mid-tempo hard-rocking 12-bar blues in G, is based on Eric's early 70's style, which is a little smoother and less aggressive than his work a few years earlier. Most of the lines are based on G minor pentatonic (G Bb C D F), with brief use of G major pentatonic in bars 8 and 9. Notice also the sharp guitar tone, fueled by the use of the bridge pickup and accentuated by a heavy pick attack.
