Watch the Diminished Sixths online guitar lesson by James Hogan from 50 Jazz Rock Licks You MUST Know
Here’s a cool lick that’s based on a harmonic device I’ve heard a lot in the playing of Scott Henderson and Michael Landau. Take the interval of a Maj 6th and move it around in the half-whole diminished scale. This is very effective when used with a bit of vibrato from either your fingers or a bar. Add an overdriven guitar sound and an altered dominant chord and you’re in business.
