G,Ab,Db,A,Bb,Eb,B,C,F,D,Eb,Ab,E,F,Bb
You can start this on any note and it works in a lot of keys. Notice that it is a 3-note motif repeated at different intervals. This is a very clever way of "playing outside" of the original key. Try different variations of this - Db,Ab,G,Eb,Bb,A,...; Db,Ab,G,Bb,F,E...; G,Ab,Db,E,F,Bb...
