The impulse which brought the "Orfeo" into being had not yet exhausted itself and the Italians continued to feast their souls on a visionary Arcadia with which they vainly strove to mingle their own present. But love of luxurious display slowly transformed their pastorals into glittering spectacles. As for the music, we may be certain that in the beginning it followed the lines laid down in the "Orfeo." It rested first on the basis of the frottola, but when the elegant and gracious madrigal provided an art form better suited to the opulence of the decorative features of the embryonic lyric drama, the madrigal became the dominating element in the music. Together with it we find in time the dance slowly assuming that shape which eventually became the foundation of the suite. Adrian Willaert became chapel master of St. Mark's in 1527 and his influence in spreading the madrigal through Italy was so great that he has been called, as we have already noted, the father of that form of composition. Certain it is that, despite the earlier publications of Petrucci, the madrigal became dominant in Italy after the advent of Willaert. But we must not lose sight of the influence of Constanzo Festa, the earliest great Italian writer of madrigals, whose first book of these compositions (for three voices) was published in 1537. We are therefore to understand that in the plays about to be mentioned the madrigal style prevailed in the music. In 1539 at the marriage of Cosimo I and Eleanora of Toledo there were two spectacular performances. In the first Apollo appeared in company with the muses. He sang stanzas glorifying the bride and her husband, and the muses responded with a canzona in nine parts. Now the cities of Tuscany entered, each accompanied by a symbolical procession, and sang their praises to the bride. The second entertainment was a prose comedy of Landi, preceded by a prologue and provided with five intermezzi. In the first intermezzo Aurora, in a blazing chariot, awakened all nature by her song. Then the Sun rose and by his position in the sky informed the audience what was the hour of each succeeding episode. In the final intermezzo Night brought back Sleep, who had banished Aurora, and the spectacle concluded with a dance of bacchantes and satyrs to instrumental music. The accounts which have come down to us note that the song of Aurora was accompanied by a gravicembalo, an organ, a flute, a harp and a large viol. For the song of Night four trombones were used to produce a grave and melancholy support. The music for this entertainment was composed by Francesco Corteccia, Constanzo Festa, Mattio Rampollini, Petrus Masaconus and Baccio Moschini. All these musicians were composers of madrigals, and Corteccia was at the time Cosimo's chapel master. In this spectacle was heard the solo madrigal for Sileno already mentioned. Here is the opening of this piece; the upper voice was sung and the other voice parts were played as an accompaniment.
