Watch the Tritone Logic online guitar lesson by Matthieu Brandt from 50 Jump Blues Licks You MUST Know
This lick is all about what I call 'Inner Logic'. This is the natural tendency of certain chord tones to make a logical move within a I chord to IV chord progression. When I'm moving from the I chord to a IV chord the major third of that I chord wants to move down to the flatted seventh of the IV chord. And the flatted seventh of the I chord wants to move down to the major third of the IV chord.
