Hi, adultpianist -
Since you've been over in the ABF, too, this thread might be of interest to you: Jazz piano discussion and ideas for beginners in jazz piano in the ABF
It'll give you some idea of the skills jazz pianists develop, and a lot
of ideas on how to do that.
The thread isn't as frequented as it was when it started, but if you post in it so that it comes to the top of the ABF it's likely that someone in the ABF will see it and respond. And jazzwee and the others are extremely helpful, and have been exactly where you are now - at the very very beginning!
The skills that classical players have definitely overlap with the ones that jazz players need, and jazzwee took some classical lessons to help develop those. But there are other skills, too, that classical pianists rarely if ever use, and jazzwee took lessons from a jazz piano teacher to specifically develop those.
There's also a thread in this forum on the Joy of Improvisation (JOI) and there are several people working thru that. You might find that interesting.
There's a new thread in the ABF on Tim Richards' Blues Piano book that might be a lot of fun for you, too.
All three of these threads are what we, in the ABF, have called "study groups." People who are working on the particular theme of the thread and helping each other out as they go.
We're a pretty friendly bunch here at PW, and especially the ABF. There's a lot in those study groups to give you some idea of what jazz piano is about.
