A 4-Note Swiss Army Knife For Improvisers
Originating from a set of well known piano voicings, these structures form a quartet of unique 4-note “scales”. Due in large part to the presence of the intervals of a minor 2nd and tritone, they offer a good deal of “bite”.
This harmonic and melodic tension was first fully appreciated by such innovators as Joe Henderson, Woody Shaw, Herbie Hancock, McCoy Tyner, et al in the early 1960s and beyond.
