Musically speaking (not necessarily in honied tones), a virtuoso nowadays is a performer who can play very fast and who, to the popular mind, looks generally like "Professor" Irwin Corey. Don't expect that sort of thing here. Originally, in Italy, the word had a much broader application: it signified an artist or scholar who had distinguished himself in his field, and was related to virtu, a term much applied to the great men of the Italian Renaissance.
