Watch the Flexible Diminished online guitar lesson by TrueFire from Play Blues Guitar 9: Advanced Lick Vocabulary
Flexible Diminished - Lick 42 is a video guitar lesson presented by Tom Wolfe and is sourced from 50 Hard Bop Blues Licks You MUST Know.
This lick also includes side-stepping to start, but then uses the diminished chord as a passing dominant chord. Wes Montgomery used the diminished voicing constantly in his solos. In this phrase the diminished chord serves as a dominant 7th with a flatted-9th. It begins with side-stepping, then the diminished/dominant passing chord to the final chords and resolution of the lick.
