In my experience, for the melody players it's mostly about the rhythym and a little about chordal context... many guitarists I've seen (some I've been) get the basic chords, but just don't feel the rhythym... But, as a lover of chordal constructs, I personally adore the interplay of chords, rhythym, and melody... and permutations turn me on! Two guitarists (or more) can work together, but compromise is necessary... interpretations ( and I believe that the chords are interpretations ) can be discordant, but not nearly as displeasing to me as hard headed ignorance of... "that's not how it goes"... comming from a closed minded and unresponsive guitarist/accompanyist... Could it be possible for accompanyists to 'follow the leader', just like the melody makers? ttr
