Heidi does have relatively long fingers, not too thin, but what is distinctive is that she always closes them, or virtually always, all the way into her palm. That way, they do not get into each other’s way. I was privileged to see many of her performances, and they were by far the most inspiring I ever saw, and I saw quite a few harpists perform in New York City. It’s no wonder she won the Avery Fisher Prize. Before Yo-Yo Ma.
