This led to further communications from Monteverde himself, prefixed to one of his later volumes, in which he declares that "harmony is the lady of the words" (signora della orazione), meaning thereby that the composer must first consider the dramatic needs of his text, and only thereafter permit himself to be governed by those of music as such.
Upon the death of the ducal music director, Ingeneri, Monteverde succeeded to the place. This appears to have been in 1603, according to the preface to the sixth set of his madrigals (in 1614), in which he speaks of having been in the service of the Duke of Mantua ten years.
The famous "representative style," in other words, dramatic music, had already been discovered, as recounted at greater length in the essay upon Italy. It is sufficient for our present purpose to compare the dates. It was about 1595 that Vincenzo Gallilei intoned at Count Bardi's his epoch-making monologue upon "Ugolino," and in 1597 the first opera, "Dafne," was privately performed at the house of Count Corsi. In 1600 the first opera, "Eurydice," the poem by Rinuccini and music by Jacopo Peri, was publicly performed upon the occasion of the marriage of Henry IV., of France, to Catherine de Medici. This work has the double honor of having been the first opera ever publicly performed and the first opera ever printed. A copy of the original edition of A. D. 1600 is now in the Newberry Library of Chicago. The fundamental problem of the new style was that of furnishing appropriate musical cadences for the impressive utterance of the words of the text. Hence the musical handling of "Eurydice" is very meagre. There is only one short instrumental ritornello, and only one short aria, of sixteen measures. Almost the entire remainder of the work is in a rather stiff and formal recitative. No attempt is made at instrumental coloring. The accompaniment is simply intended to support the voices and assure the singers of their pitch, quite after the ideas advanced by Artistoxenos, and applied universally in Greek tragedy. The tonality in "Eurydice" is almost wholly minor.
Whether Monteverde had opportunity of seeing any of these performances we have no means of knowing. At all events he may well have possessed a copy of the published "Eurydice." And so it was no doubt with pleasure that in 1607, upon the occasion of the marriage of Francesco Gonzeaga with Margherita, Infanta of Savoy, he received a commission to prepare a "dramma per musica" for the festivities. The subject chosen was "Arianna" (Ariadne), the text prepared by Rinuccini. In this work for the first time Monteverde had opportunity to give free rein to his powers. No doubt he realized that he had to present his work before hearers who had attended upon the performances of "Eurydice," and were full of its novel effects. One of his own singers, Rasi, had been engaged in the Florentine performances. The effect of "Arianna" was extraordinary, even prodigious. The aria of the deserted Ariadne, Lasciatemi morir, melted the hearers to tears. Monteverde's rival, Marco da Gagliano, who had also been commissioned to prepare a new setting of "Dafne" for the same occasion, was astonished like all the rest. G. B. Doni, in his treatise upon "Scenic Music," holds Monteverde's aria for a master-work indeed. Such was the entrance of the master into the new style. "Arianna" had a long life. As late as 1640 it was played in the theatre of S. Mose, in Venice. The success of this work naturally led to others in the new style. Hence, one year later, another opera, "Orfeo," the text by a writer not now known, and a "Ballo del Ingrate," in which, Ambros says, the music, "in spite of the ancient gods, who figure in the text, stands for the first time in the magic glow of the romantic."
Monteverde was now in the fullness of his powers. He had reached the age of forty-six. He was at once the most original of all Italian musicians of the time, and the most distinguished. Hence upon the death, in 1614, of Giulo Cæsare Martinengo, the musical director of St. Mark's, in Venice, Monteverde was called to the place, which both by reason of its celebrity as already the appurtenance of great composers for two centuries, and on account of its relation to the official life of Venice, was perhaps the most desirable one in the whole world. The salary paid the deceased conductor had been two hundred ducats yearly; that of Monteverde was made three hundred at the start, and in addition a sum of fifty ducats for expenses of removing from Mantua. In 1616 the salary was raised again to four hundred ducats, and later he was awarded the free use of a house in the canon's close. Valuable gratuities were voted him upon several occasions, as one hundred ducats, Dec. 14, 1642, one hundred and fifty in 1629, etc. Honors came fast upon him. When he was invited to Bologna, in order to direct the music for some festivity, a delegation of distinguished citizens met him a long way out upon the route, and orations and formal recognitions of the honor done the city by his accepting the invitation had full place, according to the imposing forms of the time.
In spite of the distinction which Monteverde had gained in the musical dramas already mentioned, it was not for several years after entering upon his duties at St. Mark's that he found opportunity to pursue his ideal. Between 1614 and 1624 he appeared only as church composer, excepting now and then when he produced music for a state fête, for as yet there was no public opera house in the world. In the year 1637 the first one was erected at Venice, in the parish of S. Cassiano. But previously, in 1624, the senator Girolamo Moncenigo invited Monteverde to compose a new work in the representative style, which accordingly he did, and it was privately performed in the Moncenigo palace. It was called "Il Combatimento di Tancredi e Clorinda," an intermezzo. The story was taken from Tasso's "Jerusalem Delivered," and represented Clorinda going in search of her lover, Tancred, in disguise of a young knight. Through some misunderstanding a duel between them was unavoidable, and at the moment when the swords flash and the strokes make grim accents in the pretty love story, Monteverde had the happy thought of introducing the pizzicato effect with the strings; and later when Clorinda falls, mortally wounded, the suspense is indicated by the still usual orchestral means, the tremolo. These striking effects, however, were by no means Monteverde's chief claim to memory for this work, for throughout, if we may believe the hearers (the music having disappeared), the music accurately reproduced and interpreted the feeling of the story, and the hearers were intensely absorbed, and at the critical moment moved to tears.
Another celebrated work of Monteverde was a solemn requiem which he composed in 1621, for the funeral services in honor of Cosmos II., in the church S. Giovanni e S. Paulo. Concerning this, the opera librettist, Giuol Strozzi, writes complimentarily if not clearly, that the music "depicted grief in the Mixolydian tone, the happy discovery of Sappho; and the Dies Iræ and the well intoned De Profundis, by their novelty and mastery, awakened in the hearers the greatest wonder."
From this time onward, Monteverde composed often in the new style. In 1627 he composed for the court of Parma five intermezzi; in 1629, for the birthday of Vito Morisini, a cantata, "Il Rosajo fiorito"; and in 1630, for the marriage of the daughter of his patron, the senator Moncenigo, to Lorenzo Giustiniani, he wrote to a poem by Strozzi, "Proserpina Rapita." Here again the enthusiasm of the hearers was unbounded. The magic combination of drama and song in choruses, dances, and orchestration was magical. Unfortunately almost all the operatic and church compositions of Monteverde have been lost. But his continual progress in the art of orchestration is shown now and then in the chance allusions of his contemporaries. Thus we are told that in 1631, upon the day when the votive church S. Maria della Salute was opened by the Doge (in memory of the stay of the plague), a solemn service was also held in St. Mark's, when a great effect was made in the Gloria and Credo by the resounding trombones.
As soon as a public opera house was opened in Venice, the demands upon Monteverde's talent as opera composer became more frequent. Thus followed one important work after another, until almost the end of his long and honored life. In 1642, at the age of seventy-four, he produced his last opera, "L'Incoronazione di Poppea," which had the customary effect of novelty and nobility.
Monteverde had been happily married while still living in Mantua. He had two sons, one of whom became a priest, the other a physician. Upon the death of his wife he entered the church, and took holy orders, so that from the age of sixty-five to the close of his life he was priest as well as composer and musical director. In person he seems to have been tall, rather meagre in figure, and the few existing portraits represent him as serious, perhaps even ascetic, in face. After a short illness, Monteverde died, in 1643. His funeral was held in St. Mark's, under the musical direction of his pupil, Giovanni Rovetta. But a second and more formal service was held on the 15th of December, 1643, in the Frari church, under the direction of another of his pupils, Giambattista Marinoni, musical director at the cathedral of Padua. The great master was buried in the Frari church, in a chapel at the left of the choir. No stone bears his name to mark the spot.
