i can only suggest doin improve say on a 12 bar and attack it from different directions. eg usin the mixolodion mode over each of the chords. or pentatonics resolving the notes in the chords that arnt in the pentatonic scale.
try to aproach things from dfferent angles. thats what i am tryin at the moment. i am also tryin to change between different scales natural (aeolion ) minor harmonic minor blues scale, locranion, etc
i a pickin a few at first and then tryin to expand. hopefully i wont be stuck in the diatonic box any more.
