“ Yet these were the days of singers who to us seem to be creations of overheated fancy. What marvels have we poor twentieth-century opera-goers not heard of Grisi, Mario, Malibran, Rubini, Tam-burini, and Ronconi! Yet we know it was Rubini, long the tenor idol of Paris, who introduced into the art of song the trick called the vibrato, without which no well-regulated singer now regards himself as properly equipped. The vibrato is the mother of the tremolo, that pernicious vice which leads to so much tawdry sentiment and such a wilderness of singing out of tune. ”
