Play any of the Key of G scales patterns over this D7 vamp. You can begin and/or end your phrases on the D note(Root) and A note(5th) for starters. This concept is essentially playing in the D Mixolydian mode.
This track features a Custom 7 string guitar made by Jimmy Foster. The track is a single take that has been processed to created two different sounds for the bass and treble strings. Here is a basic tab that you can view or download. This is a "six string tab" so I am not including the "D string" in this basic version. The tuning of the guitar is low to high - A E A D G B E.
QUOTE OF THE DAY
Because optimal experience depends on the ability to control what happens in consciousness moment by moment, each person has to achieve it on the basis of his own individual efforts and creativity.
