ok theory question. when you are trying to compliment a riff do you approach the riff based on the scale it is in or the chord the riff implies? or does it really matter. I've been doing some reading on the relationship between scales, chords and chord progressions and it makes sense to me when the music is chord based. not quite sure what to do when the music is riff based. I know chords are implied but sometimes the riff doesn't make sense from a chord perspective.
