"All this was a part of the steady progress toward monody, the final goal of Italian musical art, where, in extreme contrast to the Netherlandish subordination to school, the emergence and domination of individuality, the special and significant distinction of the Renaissance, were taking shape. Hence Castiglione in his 'Cortegiano' gives preference to the one-voiced song ('recitar alla lira') and it was quite natural that we find in the Petrucci collection frottole originally composed for four voices now appearing as soprano solos with lute accompaniment, the latter being arranged from the other three voices."[26] [Footnote 26: This passage is not a literal quotation, but partly a paraphrase and partly a condensation of the text of Ambros.] Castiglione (1478-1529) wrote somewhat later than the period of Poliziano. The "Cortegiano" dates from 1514, though it was not published till a few years later, and the frottola was at the zenith of its excellence in the time of Bernado Tromboncino, who belongs to the latter half of the fifteenth century. But the frottola was well established before the date of Poliziano's "Orfeo," for minor Italian composers had poured forth a mass of small lyrics for which they found their models in the polyphonic secular songs of Antoine de Busnois (1440-1482) and others of the Netherlands school, especially such writers as Loyset Compere, of St. Quentin, who died in 1518. Two of his frottole appear in the Petrucci collection, showing that he was acquainted with this Italian form, and that his productions in it were known and admired in Italy. His frottole are distinguished by uncommon grace and gaiety, for the frottola was generally rather passionate and melancholy, and full of what Castiglione called "flebile dolcezza." In view, then, of the state of part song composition in Italy at the time when Poliziano's "Orfeo" was written we are safe in assuming that its two choral numbers were set to music of the frottola type. The use of the refrains, "l'aria di pianti" in the first, and "Ciascun segua, O Bacco, te," in the second, is an additional influence in moving us toward this conclusion because we know that it was the employment of the refrain which helped to lead the frottola toward the strophic form of the song. We are, moreover, justified in concluding from the character of the final chorus that it was a ballata or dance song and hence a frottola of the carnival song variety. No student of classic literature will need any demonstration of the probability that the Maenads in their Bacchic invocation danced; and here we have in all likelihood the origin of that fashion of concluding operas with a chorus and a dance which survived as late as Mozart's "Die Zauberfloete."
