Every time I upload a video of me playing a "classical" work (Bach, Chopin, Mozart) on the piano, I get a YouTube warning and the content blocked. So far, about two dozen times, I challenge it and it comes back, but I expect someday to exceed some threshold and be gone forever.
Some of the challengers are "scam" companies, but other times it's Deutsche Gramophone or Sony.
Alternatively, you are playing from a modern typesetting of the music which has some extra notes added to detect that you are making a derivative work through your performance, like how map makers add "trap streets" to their works.
Being serious, though, I believe that a typesetting of a piece of public domain music can be eligible for copyright, but I don't believe that a performance from that typesetting can count as a derivative work of the typesetting, even if the musician faithfully performs a few "new" notes added by the typesetter.
