Ah! Right, the sharped eleventh. I forgot that jazzers like to raise it so that it fits in better (yeah, I know, that's not the technical explanation, but I never learned the why of it). LOL, I'd like to see someone do some braille music "sightreading" (I guess that's what you'd call it). You know, Wes Montgomery, my absolute favorite jazz guitarist, apparently couldn't read music at all, yet he had one of the greatest concepts of melody and harmony I've ever heard. I am constantly in awe of his work. I hope someday I can cultivate my knowledge of music and my physical chops to be able to be able to play the type of music he did. It's a shame he had to go. It seems like that happens to a lot of great musicians. Just as they begin to realize themselves, they get taken off the Earth. Oh well, I guess that's a lesson to us all to appreciate the time that we have.
