Okay, that makes sense. I play bass in a Big-Band, and some of our newer charts are this way, including some Metheny arrangements.

I'm fine with it, and might even lean towards saying it's easier to sight read, but on the other hand, I've spent decades reading traditional, so I'm used to that too. And on a jazz chart, I can ad-lib if needed to keep the show going if I get confused by something. My hands will usually gravitate to the right place even if my brain is wrong.
