No, unless the current composer for the game decides he want to work with one.
But, we should have a pianist in-game. A gnome bard who travels on a little cart that folds down to reveal the piano. The cart is pulled by a rothe who provides the mood lighting during performances. It's mostly smooth jazz.
Its fun idea.
I think it should work via Narrator. I liked AC Valhalla's boat trips as you could ask them to sing and tell stories. I wouldnt mind to see something similiar in BG3, it tend to get boring quite easily.
