Watch the Chromastern online guitar lesson by Tom Dempsey from 50 Jazz Master Licks You MUST Know
As jazz evolved into the late 60s and early 70s there were influences coming in from rock and popular music. The music that was evolving in jazz was known as fusion. The sound of the guitar was also influenced by adding effects and playing solid body and semi-hollow body guitars instead of the big hollow body instruments. One of the influential voices leading this charge was Mike Stern. He played with Miles Davis during Miles' come back. One of the aspects of Mike's sound, especially playing straight ahead jazz, is the presence of chorus and delay in his sound. It does fatten the notes in an interesting and modern way. Another aspect of his playing is how he connected chromaticism in his long flowing eighth note lines. Check out this example of a Mike Stern influenced line over a the last four bars of a blues. Notice the shape of the chromaticism here.
