From the first time the Three Tenors stepped up to a microphone and began belting Broadway tunes, discriminating listeners have known that there is a serious disconnect between the vocal styles of classical musicians and, well, everyone else. In fact, the real failure of the “crossover” genre is not that it has dumbed down the classical market, but that the singers almost always sound like fish out of water, says Richard Dyer. “Too many opera singers have had the wrong tonal quality, the wrong diction, the wrong rhythm — and the wrong arrangements. There is a kind of arrangement that knows no period; Las Vegas lies in a land beyond time and place, and that’s where the hearts of too many arrangers lie.”
