no the real problem is that the important guitarists (Django, Hendrix, Jansch) are largely musically illiterate.

Some like Django and Bert dallied with learning notation, and it seemed to subtract rather than add.

Musical literacy is important for ensemble playing - but the geniuses, the wildcards like Bix Beiderbeck and Lightning Hopkins - seemed better without that stuff in their heads.

its best left to the individual. no blame one way or the other.
