Jazz is the big brother of the blues. If a guy's playing blues like we play, he's in high school. When he starts playing jazz it's like going on to college, to a school of higher learning.
I don't really worry about the size of the part much any more. It's nice to have more time to work on the character, and to have big scenes to play. But if there's something playable there, and if it's interesting to do, then that's nice.
I think what I've recognized over the years is that I'm very, very bingey, extremely bingey when it comes to writing.
