. . . as well as getting out and listening to groups live.Also, take advantage of any opportunities you can to actually play with experienced jazz musicians. Try to get to a jam session and get up and play, even if it feels awkward for a while. Once you turn up a few weeks in a row, you'll be part of the scene and it will be much more comfortable.
Just don't try to get too far in over your head and get frustrated to the point where you want to quit. Maybe have a conversation with some of those players and tell them what you're trying to accomplish. There are a lot of very friendly musicians open to helping others get better, but there are also some people who would rather you spend that time learning elsewhere. In my opinion, it's best to know that because as fantastic and fulfilling as one scenario is, the other is equally strong in the opposite direction. I know that from experience.With all of that in mind, it's also worth seeking out playing opportunities where you feel a bit out of your depth. If you're completely comfortable, it might be that you don't stand to learn much. You want to make sure that you're playing with musicians with rock-solid time and a good groove!
