That there was some sort of an orchestra in the "Orfeo" is probable, though it is not wholly certain. The letter of the Envoy Pauluzo on the performance of Ariosto's "Suppositi" at the Vatican in March, 1518, has already been quoted. From this we learn that there was an orchestra containing fifes, bag-pipes, two cornets, some viols and lutes and a small organ. It is a pity that Pauluzzo did not record the number of stringed instruments in order that we might have some idea of the balance of this orchestra. On the other hand, as there was no system of orchestration at that time, we might not learn much from the enumeration. Rolland, in commenting on this letter, says, as we have already noted, that this was the type of musical plays performed in Italy at least as far back as the time of Poliziano. There is no imperative demand that Rolland's statement on this point should be accepted as authoritative, for his admirable book is without evidence that the author gave this matter any special attention. On the other hand it is almost certain that his assertion contains the truth. All the instruments mentioned by him were in use long before the date of the "Orfeo." Furthermore assemblies of instruments played together, as we well know. But we are without data as to what they played, and are driven to the conclusion that since there was no separate composition for instruments till near the close of the sixteenth century, the performance of the early assemblies of instruments must have been devoted to popular songs or dances of the time. A little examination into the character of these early "orchestras" may serve to throw light on the nature of the instrumental accompaniments in Poliziano's "Orfeo." Symonds's description of the performance of Cecchi's "Esaltazione della Croce," already quoted in Chapter III, shows us that in 1589 a sacred representation had an orchestra of viols, lutes, horns and organ, that it played an interlude with special music composed by Luca Bati, and that it also accompanied a solo allotted to the Deity. Another interlude showed David dancing to lute, viol, trombone and harp. It is evident, therefore, that at a period a century after that of the "Orfeo" there was a certain sort of orchestra. But this period was somewhat later than that of Striggio, who had already employed orchestras of considerable variety. In his "La Cofanaria" (1566) he used two gravicembali, four viols, two trombones, two straight flutes, one cornet, one traverso and two lutes, and in a motet composed in 1569 he had eight viols, eight trombones, eight flutes, an instrument of the spinet family and a large lute, together with voices. To delve backward from this point is not so easy as it looks, yet however far back we may choose to go we cannot fail to find evidences that assemblies of instruments were employed, sometimes to accompany voices and again to play independently.
