Not a freebie, but an amazingly good piano... DAZ's Music Room features a great grand piano that opens up, and even has a music stand that folds down. I used it in the picture linked below. It's a bit zoomed-in due to how I wanted to have the picture laid out, but you can get a decent idea of it, at least.
