Of course you always say farewell to something or someone. (In this case it was farewell to my male partner of 10 years, R.W.) I wrote the piece soon after our breakup in a wistful moment (3 1/2 hours). As I wrote I was feeling neither happy nor sad but almost serene. And because I was writing for my consummate artist friend I decided, as well, to make the piece virtuosic. But — and this is a specialty of Hilary Hahn — virtuosity in the service of enhanced expressivity.
