This is so interesting to me -- including the prior remark by keyofc.
I am 66 years old and play at -- maybe early advanced level?
I did have a very elderly teacher who I liked a lot but was just injured in a fall and will not be able to return to teaching. So now I have a new teacher.
The elderly teacher (80?) more or less just listened to me play, and picked up on major errors. She was more of a "contributing audience of one." No one else really hears me play except the cats. Unlike some of the most stubborn adult students, I did work to try to correct the problems she revealed to me. I remember playing a couple of staves of Bach what seemed like a million times . . . !!
My new teacher is a young woman with a piano performance major, recently graduated. She is a gifted pianist -- really good.
I don't try to show off to my teachers, because I know what GOOD really means, and certainly they know. So playing mid-level piano works competently may seem GOOD to the neighbor lady who happens to hear me play. But there are degrees of GOOD, and it takes some real knowledge to know what GOOD means with piano.
Mainly I do enjoy being able to prepare material to take to my lesson, and I enjoy having someone who plays listen to what I am working on. I'm glad for some advice, and some projects for improvement.
But as for GOALS now - - - - I told my young performance wizard -- put yourself in my place, I'm old. No more recitals for me. No cheering crowds. No dreams of a career in music. I just love to play, and it is a nice enterprise for me. I want to get better. But in a relaxed, amiable sort of way.
Don't try to get me to replay a stave of notes again and again to get that unteenth little touch of extra polish. I may not even have it in me. On the other hand, if I am getting my thirds all out of kilter by playing them at the wrong tempo, well . . . lets work on that.
When I come to my next lesson, I always play at least some of the material she has coached me on, as if to say . . . you see, I do pay attention, and I do respect your teaching. But then I may pull out something she has never heard me play and say, "do you mind if I play this for you?"
Sorry this is so long .......................
