Clearly, it's a matter of interpretation. But even if I could play this fast, I am not sure I would.
I got about 20 minutes or so to experiment with Stella yesterday. It's a slow start, I must say. I don't expect to be able to sight-read this material, but at this point in my development, getting up and going on the new patterns for each new piece is a slow process. And to be honest, I don't really enjoy it.
