Watch the Slow Blues: Ex. 1b online guitar lesson by Andy Aledort from Kings of Blues & Rock Vol. 6: T-Bone Walker

This segment represents the second half of a standard 12-bar blues progression (bars 7-12), beginning with two bars of the I chord, G7, followed by one bar each of the V chord, D7, and the IV chord, C7, wrapping up with G7-C7-G7-D7 across the last two bars. The segment ends with the chromatically descending chords Ab9-to-G9, a staple of the T-Bone sound.
This segment begins with phrases based on 16ths and 16th-note triplets, similar to the previous example; some interesting twists are the quirky half-step bends in bars 2-into-3 of the example, followed by the "two against three" feel (accentuating a feel of two eighth notes against the time signature of eighth-note triplets) in bar 4 of the example.
