Watch the Sweet Angel: Ex. 3b online guitar lesson by Andy Aledort from Kings of Blues & Rock Vol. 4: B.B. King
This example picks up where the last one left off, back over the I (one) chord, Db7, and then to the V7, Ab7, the IV7, Gb7 and then the turnaround. There are many beautiful "B.B. King"-isms in this solo, such as the chromatically descending lines at the end of bar 1 into bar 2, the shift from Db minor pentatonic in bar 3 of the example over the V7 chord to Db major pentatonic in bar 4 of the example over the IV7 chord, and the arpeggio-like phrases that culminate the solo in bars 11 and 12.
