[Footnote 28: "Although the existence of 'Orfeo' as an opera appears to me to be problematical, there would be nothing impossible about the construction of a tragedy accompanied by music, because instruments were cultivated in Italy more than in France. Before that epoch the Medici had given concerts at Florence. Giovanni de Medici died in 1429, and Cosimo, who succeeded him and reigned till 1464, gave at the Pitti Palace concerts where there were as many as four hundred musicians. Under his successors and before the death of Alexander de' Medici in 1537, the violinists Pietro Caldara and Antonio Mazzini were often the objects of veritable ovations, and about the same time, 1536, at Venice, was played a piece called 'Il Sacrificio,' in which violins sustained the principal parts."--"Les Origines de l'Opera et le Ballet de la Reine," par Ludovic Celler. Paris, 1868.] While, then, it must be confessed that no conclusive evidence can be produced that an orchestra was employed in the "Orfeo," the indications are strong that there was one. We may assume without much fear of error that it was used only to accompany the choral numbers and the dance and that in fulfilling the last mentioned function it was heard to the best advantage. Years after the period of the "Orfeo" of Poliziano independent instrumental forms had not yet been developed. Fully a century later compositions "da cantare e sonare" betray to us the fact that bodies of instruments performing without voices merely played the madrigals which at other times were sung. Such compositions were not conceived in the instrumental idiom and must have floated in an exceedingly thin atmosphere when separated from text and the expressive nuances of the human tone. But the music of the dance was centuries old and it had in all eras been sung by instruments, as well as by voices. The invasion of the realm of popular melody by crude imitations of the polyphonic devices of the Netherlanders could not have crushed out the melodic and rhythmic basis of dance music and this had fitted itself to the utterance of instruments. We are therefore justified in believing that if the accompaniment of the first chorus in the "Orfeo" was superfluous and vague that of the final ballata must have been clearer in character and better suited to the nature of the scene. The dance following the ballata must have been effective. The instruments were most probably lutes, viols, flute, oboe, and possibly bag-pipe, hurdy-gurdy and little organ.
