Am I doing a disservice to Beethoven, e.g., by playing his sonatas as an amateur?
Hardly, more like doing him a service by perpetuating his art.. Just that rather than it perhaps being enjoyed as from the perspective of a listener in the exact way he intended, its enjoyed as a student by learning from it.You're never good enough. No one is. There is always something that is only just outside your reach that there would be no point in saying "I could never do that" to. Further, art is a creative pursuit that exists to express ones emotion. It is a pursuit to express the verbally inexpressible, but it is also usually a snapshot perspective, meaning that the same story can be told over and over from different angles, and differently as you grow with it. Being done with art is like being done with life.You can be satisfied with you're level of learning on a piece at a particular stage in your development as musician, but that doesnt mean that you should never touch the piece again or that you won't play it any better than that down the track. They are like memories, you don't just recall them 10 times and then you're done, as if its possible to relive the memory in an ideal way. They stick with you forever.. if you let them.
I am never going to be a concert level pianist, but I'm wondering how do you know when you've learned something "good enough"?Am I doing a disservice to Beethoven, e.g., by playing his sonatas as an amateur?
