I've suddenly felt an improvement in my piano playing. My fingers are finding better chords with both hands, and I can actually improvise a bit. I've been trying to break out of a mechanical mode in which I was always playing the root, third, and seventh in my left hand and playing a melody in my right. That worked for me up to a certain point but it is much better to play root and seventh, and then a third and a ninth or 13th above that, or skip the root all together. Although I've known this in theory for a long time, it is hard to break out of a comfortable habit.
For example, my E flat flat seven is Eb / Db / G / E.
I still have a long way to go. I could tell you all the things I still can't do. It is strange though that I feel just as positive about those things, seeing them in my future.
As kids we imagine flying, and flight in our dreams feels very real and possible. We can also fantasize about doing other things that seem barely possible. What if there is a thing that is as fantastic as flight, but actually plausible as a human skill? That's what piano playing is for me.
