Indeed, even some of the earliest Italians recognized this. Caccini, at the beginning of the seventeenth century, broke away from the contrapuntal music of the church because it made the words unintelligible. Tosi, who published a vocal method in 1723, a little less than a century and a quarter after Caccini's declaration, still insisted on the importance of clear diction. "Singers should not forget the fact," he wrote, "that it is the words which elevate them above instrumentalists." But with the introduction into Italian music of florid ornamentation, which of itself made the words more or less unintelligible, they lost their due importance, until, as many an old opera-goer still can testify, a tenor like Brignoli could, without protest, habitually allow himself the liberty of substituting "la" for the words on all high notes and phrases, simply because he found it easier to sing them on that syllable. At song recitals, the words of the songs often are printed on the programmes. Printed translations of words sung in foreign languages serve an obviously useful purpose. But when an English-speaking singer prints the words of English songs on his programme, it virtually is a confession that he does not expect his hearers to understand what he is singing to them in their own language--so rooted in singers has become the evil of indistinct pronunciation. Their songs are songs without words. However, there has been an improvement in this respect. The old-time opera libretto was so stupid that Voltaire was justified in saying, "What is too stupid to be spoken is sung." But with Wagner the importance of making the words clear to the hearer was recognized, and since his works have established themselves in the repertory of the operatic stage, and modern opera composers, following in his footsteps, have striven to write music that would express the dramatic significance of the words to which it is composed, the art of libretto construction has greatly improved, and composers demand that the singer shall convey to his audience some idea of what is being sung.
