Hey Doug,
what I do sometimes to get my students to stop thinking of "Rootville" is first break the tune down into arpeggios, then I tell the student for an exercise is to know where the roots are in time, but you cannot play the root, you must play only thirds and fifths and sevenths first, then you can add the root as a passing tone. so base some patterns built off of the root without trying to always start on the root--see the patterns around the root. this system is what a lot of good melody players do because always starting on the root can sound trite and amateurish especially in a solo. once he is comfortable with the arpeggios, then you can fill in with scales and pentatonics based off the root and the fifth of the chord is really cool too.
Good idea.Thanks for that
