There are a couple of observations I can make so far.
1. On my way into this frame of mind, I was cluing into my own listening, and felt that I knew I was truly listening when I could hear what was to come next, actually.
2. I gave myself permission (which is tricky to do

) to do whatever under the sun I wanted to do, so long as I did it with a clear intention, and I believe it included the kind of listening I mentioned above. I think this resulted in what feels like improvisation to me, but could be described as being in the moment, which I believe is what makes music into something "living."
3. Within that, though, upon listening back, I heard things that made me realize I didn't actually fully throw out suggestions from teachers, or stylistic ideas. I mean, there are some things that are there that were there in this recording better than normal, like balance between hands, for one. So, here is where my fascination really kicks in. How could I have given myself permission to do whatever I want, yet I chose to do something which I am "supposed" to do? It made me realize something ... "interpretation" is perhaps about "elements" ... and certain composers and styles have certain elements within their pieces which their own creative minds use. But, they are doing it strictly as a creative force, similarly to me playing it with my imagination. There were more realizations surrounding that as it relates to all things pianistic/musical.
But, I start to see how I can take these elements myself, similarly to when I was little and separated out all the lincoln log bits to create something with, and use my imagination to create things with.
Another thing that struck me is that I have numerous scalar figurations which are generally pretty clean. I've practiced this with a metronome, I practice scales everyday, I aim at clarity ... yet these were not my goals at the time. I was simply having fun and expressing myself as I strictly wanted to. Yet, some measure of cleanliness came out. So I wonder, since I like cleanliness in my playing, how did I actually arrive there? Was it because I was just playing around and not making a big deal of that, or was it precisely because I've made a big deal of that in other ways to the point that I could play around with it? If I think in elements, and I think of a clean run as an element that I can choose to do something with, I can make some sense in there and start to have a whole different sense about music and music fundamentals in general.
In any event, what I think overall is that there is some corner here that I want to more fully turn.
