How far removed this species of lyric solo was from the dramatic recitative of Peri and Caccini is apparent at a single glance. But on the other hand it is impossible to be blind to its relationship to the more metrical arioso of Monteverde's earlier work or perhaps to the canzone of Caccini's "Nuove Musiche." The line of development or progress is distinctly traceable. At this point it is not essential that we should satisfy ourselves that the solo songs of Caccini were descendants of the lyrics of the cantori a liuto, for when the two species are placed in juxtaposition the lineage is almost unmistakable. What we do need to remember here is that the method of the lute singers entered fully into the construction of the score—if it may be so called—of Poliziano's "Orfeo" and passed from that to the madrigal drama and was there brought under the reformatory experiments of Galilei and his contemporaries. This subject must be discussed more fully in a later chapter.
The first lyric number of the "Orfeo," that sung by Aristæus, is plainly labeled "canzona," and was, therefore, without doubt a song made after the manner of the lutenists. The words "forth from thy wallet take thy pipe" indicate that a wind instrument figured in this number. What sort of instrument we shall inquire in the next chapter. At present we may content ourselves with assuming that no highly developed solo part was assigned to it. The existence of such a part would imply the co-existence of considerable musicianship on the part of the pipe player and of an advanced technic in the composition of instrumental obbligati. It might also presuppose the existence of a system of notation much better than that of the fifteenth century. But this is a point about which we cannot be too sure.
The decision must be sought in the general state of music at the time. The learned masters cultivated only a capella choral music, and the unlearned imitated them. There was no systematic study of instrumental composition. Even the organ had as yet acquired no independent office, but simply supported voices by doubling their notes. It seems unlikely, then, that the pipe in "Orfeo" could have had a real part. What it probably did was to repeat as a sort of ritornello the clearly marked refrain of the song. This would have been thoroughly in keeping with the growing tendency of the frottola to use refrains and advance toward strophical form.
The lyre, with which Baccio Ugolino as Orfeo accompanied himself, may have been a cithara, but the probabilities are that it was not. As late as the time of Prætorius's great work (Syntagma Musicum) the word "lyra" was used to designate certain instruments of close relationship to the viol family. Prætorius tells us that there were two kinds of Italian lyres. The large lyre, called lirone perfetto, or arce violyra, was in structure like the bass of the viola da gamba, but that the body and the neck on account of the numerous strings were somewhat wider. Some had twelve, some fourteen and some even sixteen strings, so that madrigals and compositions both chromatic and diatonic could be performed and a fine harmony produced. The small lyre was like the tenor viola di braccio and was called the lyra di braccio. It had seven strings, two of them outside the finger board and the other five over it. Upon this instrument also certain harmonized compositions could be played. The pictures of these two lyres show that they looked much like viols and were played with bows.[27] An eighth century manuscript shows an instrument with a body like a mandolin, a neck without frets and a small bow. This instrument is entitled "lyra" in the manuscript. If now we come down to the period when the modern opera was taking form we learn that Galilei sang his own "Ugolino" monody and accompanied himself on the viola. Various pictures show us that small instruments of the bowed varieties were used by the minnesingers, and again by jongleurs in the fifteenth century. Early Italian painters put such instruments into the hands of angels and carvers left them for us to see, as in the cathedral of Amiens. In fact there is every reason to believe that the wandering poets and minstrels of the Middle Ages used the small vielle, rebek or lyre for their accompaniments much oftener than the harp, which was more cumbersome and a greater impediment in traveling.
