I agree with all that has been said here and the resulting sounds from playing up the neck and/or in open tunings are varied and tuneful, often adding depth and expression to the music.

What I do not like are those (few) guitarists who play jazz/blues chords which, very often, do not suit the tune being played.

It seems to me that often they do not know the tune and are just playing chords that they hope will fit by jumping up and down the neck, resulting in a lot of dischords. Obviously the chords they play do, quite often, and I think mainly by accident, end up sounding all right.

OK Whinge over.
