Shouldn't it be "the piano"? Shouldn't we use"the" with musical instruments in English?
I don't think an English speaker would say this but they might say " I play the piano very well". For some reason, I don't know why, we always put a word before well, quite well, reasonably well, very well but not well on its own.
That is fascinating. Since it runs from 1800, it does not seem to be Am. as against Br. Usage. "Nice" on its own sounds very strange to me but it must be a bee in my own bonnet. Thanks for checking it up. I must ask friends do they play the piano and listen to the answer! :-)
The intonation of the Greek audio sounded like a question to me, so "Do I play piano well?" Or am I mishearing?
