Re: Jazz is all mistakes
In truth, it's sad to see that Jazz has degenerated into that. I'm a huge fan of Big Band swing like Glenn Miller, Benny Goodman, etc, and the music was always spot-on.
Some years ago, I picked up a Glenn Miller Orchestra CD with Mel Torme and Manhattan Transfer doing classic GM songs with the original orchestra. Mel TOrme is old-skool, so his singing was on-target. Manhattan Transfer completely butchered the harmonies in "Kalamazoo" and "Pennsylvania 6-5000" by going off-key.
I returned the disc that day, demanding an exchange or refund. When they asked why, I informed them that this was "Jazz", not "Swing". The guy behind the counter (whom I knew to be a knowledgable musician) said "they're the same thing". So then we entered into a discussion on why they were not the same thing, at least in modern times. I won, and got an exchange for a CD that was cut from the original 1940s recordings.
I'm sure it is quite difficult as a Jazz player to convince yourself to play the wrong note, having spent so much time learning the various scales and modes and theory, and I've often heard players say "oh well, it's an inside joke". The thing about inside jokes is that everyone on the outside thinks you're an idiot.
I'd seen Joe Pass hailed by Guitar Player as a legendary Jazz guy, but never really heard anything form him, so I picked up a CD - 6-string Santa (it was Christmas, and the local shops just don't have a wide selection). This guy was a Jazz legend? Off-notes in every track! I was nont amused. Les Paul didn't have all this slop!
I just don't see the logic in it. If you can play it "right", why would you intentionally play it "wrong"?
