hmmmm.... well, it depends, I guess

.
I consider myself a 'person', first, who expresses my personal sense about life through music -- including piano playing. Sometimes the next "problem" for me as an individual, and as a musician/pianist, is not so much about how to play something in particular, but rather how to think about the world and how to
be, as strange as that may sound. And, whatever a person would label it, I don't consider myself to be asking "philosophical" questions, but rather, I am just working out my next "problem."
It seems necessary for me to be aware of and take care of the needs of the 'greater,' and the rest will more or less fall into place. So, when it comes to piano playing and piano technique, I think in terms of the entire body. In my experience, beliefs and observations, however, our minds and the way we think are even
greater -- or at the very least, extremely tied in. What we think can affect everything we do in life, and of course, how we interpret music, but even how we hold ourselves in body-form. Posture is very much psychological, and our psychological makeup is extremely tied to the world -- more than many people even care to know about right now.
The rest of all that is pretty difficult for me to explain at this point in my life -- or maybe I am just feeling particularly lazy right now ... hee hee.
As with everything, there is a need for balance, of course, but that's up to each individual to discern what that is for themselves.
