Dr. Burney (no mean authority) said, Gluck was the Michael Angelo of living composers, and called him the simplifying musician. Salieri told me, that a comic opera of Gluck's being performed at the Elector Palatine's theatre, at Schwetzingen, his Electoral Highness was struck with the music, and inquired who had composed it ; on being informed that he was an honest German who loved old wine, his Highness immediately ordered him a tun of Hock.
