This has a feel reminiscent to the Miles Davis track “Jean Pierre”. Great for open-ended, anything-goes jamming in E. It is basically a static E7 chord with some extensions thrown in for “jazziness”.[audio:http://guitarteacher.com/media/mp3/jam/funk_e.mp3|loop=yes]
Here are a few scale suggestions:
The F Diminished scale give you the E Half Step/Whole Step Diminished Scale which is gives some nice color notes against the static Dominant chord.
