Division into Acts
The division of their dramas into acts seems to have been a much simpler proposition for the librettists than adherence to the unities. To begin with, they had only two choices: three acts or five. Classical precedent as articulated by Horace was unambiguous: five-act division was the accepted norm for ancient drama.[30] But strong competition was readily available from the living tradition of the cornmedia dell'arte as well as from Spanish drama, with their three-act structures.[31] By its very simplicity, in fact, the choice between five or three acts focused the librettists' dilemma with particular clarity. It demanded a commitment, one that could not be hedged. Whatever the decision, it was an immediate confession that classical precedent either was or was not being followed. Given librettists' alleged discomfort with the necessity of abusing the unities, it is surprising how few of them chose the five-act format.
We have considered the defense by the librettist of Le nozze d'Enea of his five-act format on the basis of verisimilitude: five acts offer twice as many intermissions as three, hence twice as many opportunities for the audience to imagine the passage of time. It is interesting that this author does not even attempt to cite classical authority for his choice, but somewhat sheepishly acknowledges the modern preference for three acts. Busenello, on the other hand, justifies the five acts of his Giutio Cesare (1646) with a perfunctory bow to classical precedent: "If the acts are five and not three, remember that all ancient dramas, and especially the tragedies of Seneca, are divided into five acts" (Appendix I.12a). But Giulio Cesare happens to be Busenello's only five-act libretto.[32] And, as we have seen, he shows no compunction in dismissing classical precedent in the prefaces to his other librettos—and even in the preface to
Giulio Cesare with respect to other issues. Busenello reveals his true nature here, and the true functioning of his education. For him and his fellow academicians, the entire arsenal of precedent existed to be used or discarded as needed. And the needs changed frequently. What passed for legitimate one day failed the next. In any case, five-act librettos were exceedingly rare in Venice, even in the early years of generic insecurity.[33]
Three acts may have been the accepted norm for modern opera librettos (as they were for Spanish drama and cornmedia dell'arte ), but at least one of our early authors was moved to justify his choice. In the preface to his first libretto, Delia (1639), Giulio Strozzi claims three-act division as natural: "I have divided the work quite deliberately into three acts, a division common to all things: beginning, middle, and end"; and he defends it against the silent proponents of the "classical" five acts by distinguishing between ancient drama and his own work: "The ancients made five in theirs, because they interspersed them with singing [i.e., choruses]. This work, being wholly sung, has no need of so many pauses" (Appendix I.15e).[34]
After the early 1640s, the three-act division, a clear bow to modern taste, became completely conventional for dramma per musica ; five acts, however, remained the norm for spoken dramas.[35] The issue did not arise again until the end of the century, when a few of the most radical neoclassicizing librettists, especially Frigimelica Roberti, but also Zeno, used five-act division as an emblem of their orthodoxy.[36]
