Just starting my 4th year, 1-2 hrs / day 7 days a wk. The last 4 months have been a big jump for me since I'm engrossed with the Modern Jazz Quartet, mainly John Lewis, what a master.
What I don't know is where to go from here since I think I need some variation. Any ideas would be helpful for this very late bloomer.
Frank, you're putting in good time every day and you're clearly enjoying what you're doing. Before I say anything else, for transparency, I am a teacher and that's the perspective my advice comes from.
Teachers love students who really want to learn. Depending on where you are you might check with local universities. If your in a city or a place where jazz musicians are plentiful maybe you could connect with them. The musicians who are playing jazz in clubs probably know who the good teachers in jazz are (in your area). There are a lot of excellent teachers on Skype. It's just a question of looking around and doing the research. As you identify teachers don't settle for one who doesn't enjoy teaching you as much as you enjoy playing the piano.
We often think of teachers as helping us to play an instrument. But another way to look at it is teachers help us to learn how to practice an instrument. So a good teacher can help you really get the most from all of that time and energy you're putting into the piano. And 1 to 2 hours a day 7 days a week is good chunk of time! A great teacher will save you an enormous lot of time. Which means you'll also be able to get maximum benefit from the time you put into the piano.
Here's a link on Youtube with what looks like a million uploads of classic jazz recordings. And some great recordings too that aren't that well known.https://www.youtube.com/watch?v=dQ0A_JLdOYs
And there are a lot of pianists on these forums who can suggest ways to go as well.
Hope this helps!
