Hand in hand the technic and the art of descant had come down the years. The sharp distinction early made between "contrapunctus a penna" and "contrapunctus a mente" showed that composers and singers to a certain degree actually stood in rivalry in their production of passage work for voices. The rapid expansion of the florid element in the polyphonic music of the composers indicates to us that the improvised descant of the singer had a sensible influence. We need not be astonished, then, to learn that long before the end of the sixteenth century a very considerable knowledge of what was later systematized as the so-called "Italian method" had been acquired. The registers of head and chest were understood, breathing was studied, the hygiene of the voice was not a stranger, and vocalizes on all the vowels and for all the voices had been written. Numerous singers had risen to note, and the records show that their distinction rested not only on the beauty of their voices and the elegance of their singing, but also on their ability to perform those instrumental feats which have from that time to this been dear to the colorature singer and to the operatic public. In the closing years of the sixteenth century we find that the famous singers were heard not oftener in public entertainments than in private assemblies. Occasionally a madrigal arranged as a solo figured in a lyric play, but the singing of madrigals for one voice was a popular field for the exhibition of the powers of celebrated prima donnas such as Vittoria Archilei and eminent tenors like Jacopo Peri. Kiesewetter[35] gives a madrigal sung as a solo by Archilei. The supporting parts of the composition were transferred from voices to instruments apparently with little trouble. Mme. Archilei herself played the lute and her husband, Antonio Archilei, and Antonio Nalda played two chitarroni. The music of the madrigal was composed by Signor Archilei. Here are the opening measures of this lyric: [Musical Notation] [Footnote 35: "Schicksale und Beschaffenheit des Weltlichen Gesanges," by R. G. Kiesewetter. Leipsic, 1841.] Here is the beginning of the composition as Mme. Archilei decorated it with her extraordinary skill in the vocal ornamentation of the period: [Musical Notation] We are told that despite the fine professions of the Florentines, Mme. Archilei was permitted to embroider Peri's _Euridice_ in something like this fashion. But we must admit that even in those days a prima donna had power, and that something had to be conceded to popular taste. Furthermore, we shall see that the Florentines did not purpose to abolish floridity entirely. CHAPTER XV The Medium for Individual Utterance
