When you start out playing the piano, there is quite a bit of social incentive to do so.
Once you reach a stage where you can walk up to a piano and play something decent, that gives you a fun skill to show off. However, once you get past a certain point, it all seems to be very similar to the layman (or not? music is complicated.)
You spend hundreds of hours, often making subtle improvements which often aren't apparent to someone in the audience.
There's virtually no difference in a lot of situations between playing decently and playing amazingly well, because listeners need to be paying attention and/or have a musical ear to tell the difference.
The more musically interesting pieces you try to spend time on will be less interesting to most people than a cliched Chopin waltz.
Music becomes increasingly subjective. At the starting, the basics of phrasing etc are almost "universal", in the sense that there is to a large extent a concept of what sounds better or worse, which will be apparent to many people and generally accepted. Not in the sense of an authority governing it, but people will just "know" intuitively when something is musical or not, and the reason for that boils down to such concepts which are tacitly acquired.
If you play completely for your own satisfaction, it feels like you miss out on the communication aspect of it. If you play to communicate it to other people, however, the a majority of people will not get the music beyond a rather superficial level, so you feel defeated.
Then, do you play for other pianists, or critics, or people who you in general believe truly understand music?
Or on the other hand, do you believe that a truly good piano performance is like a shining beacon of light, self-evident to anyone who sees it?
What motivates you to keep improving once you are at that point? Why do you keep playing?
I wonder, by the way, how many pianists here are advanced but don't post in the topic because they think they aren't advanced enough? I remember going to a piano course where you could choose between the "advanced" and the "intermediate" group, and basically everyone tried to pick the "intermediate" group even though they were advanced
I like the philosophy of Japanese grand master archer Hideharu Onuma: "Sometimes we will hit the target, but miss the self"What does it really mean to hit all these music targets but miss yourself? What does music mean to you, to merely play more difficult works? What do you do once you hit all these targets where do you go? Is merely hitting targets all you want to do? What if the target is no longer in your mind and you merely shoot into the darkness to hit it? Those strikes you hear hit in the darkness pulsates a type of energy that sustains a precious oasis of creativity within us. "shooting with technique improves the shooting, but shooting with spirit improves the man."
