We read frequently that the first instance of solo singing was the delivery of a madrigal of Corteccia in a play of 1539. The character Sileno sang the upper part and accompanied himself on the violone, while the lower parts were given to other instruments. But this was nothing new. This kind of solo was considerably older than Sileno and the performance of Baccio Ugolino in Poliziano's "Orfeo" was unquestionably of the same type. And this manner of delivering a solo, which Castiglione called "recitar alla lira," was a descendant of the art of singing with lute accompaniment which was well known in the fourteenth century.

Doubtless Casella, who was born in 1300 and set to music Dante's sonnet "Amor che nella mente," was one of the cantori a liuto. Minuccio d'Arezzo, mentioned by Boccaccio, was another. Here again we must recur to the observations of Burney and the examinations of Ambros. The former records that in the Vatican there is a poem by Lemmo of Pistoja, with the note "Casella diede il suono." It is likely that this musician was well known in Italy and that he would not have had to rely for his immortality upon the passing mention of a poet if the art of notation had been more advanced in his day.

The story of Minuccio, as told by Boccaccio, is this. A young maiden of Palermo, seized with violent love for the King, begged Minuccio to help her. Not being a verse-maker himself, he hastened to the poet Mico of Siena, who wrote a poem setting forth the maiden's woes. This Minuccio set at once to exquisite and heart-moving music and sang it for the King to the accompaniment of his own viol. The poem is in the main strophic and the melody is of similar nature. Whether Boccaccio or Mico wrote the poem matters not in the historical sense. The important facts are that such a poem exists and that a hint as to its music has come down to us.

In the "Decameron" we are told often how some one or other of the personages sings to the company. Sometimes it is a dance song, as for example the "Io son si vaga della mia bellezza." To this all the others spontaneously dance while singing the refrain in chorus. Another time the queen of the day, Emilia, invites Dioneo to sing a canzona. There is much pretty banter, while Dioneo teases the women by making false starts at several then familiar songs. In another place Dioneo with lute and Fiametta with viol play a dance. Again one sings while Dioneo accompanies her on the lute.

Thus Boccaccio in his marvelous portraiture of the social life of his time has casually handed down to us invaluable facts about vocal and instrumental music. There is no question that Ambros is fully justified in his conclusion that the cantori a liuto were a well-marked class of musicians. They were vocal soloists and often improvisatori, clearly differentiated from the cantori a libro, who were "singers by book and note" and who sang the polyphonic art music of the time.

It is pretty well established that the songs of Dante were everywhere known and sung. We have reason to believe that many of those of Boccaccio were also familiar to the people. We may also feel confident that when most of the Italian lute singers of the time had acquired sufficient skill to make their own poems as well as their own melodies, they followed the models provided in the verses of the great masters. What is still more important for us to note is that these lyrics were strophical and that they were no further removed from the folk song of the era than the frottola was. Indeed they bore a closer resemblance to the frottola. They differed in that they were solos with instrumental accompaniment instead of being part songs unaccompanied.

But this difference is not so important as it appears. The part song method was at the basis of all these old lute songs. This is well proved by the fact that before the end of the century the device of turning part songs into solo pieces with lute accompaniment had become quite familiar. It was so common that we are driven to something more substantial than a mere suspicion that Casella and Minuccio employed a similar method and that the domination of polyphonic thought in music had spread from the regions occupied by the church compositions of Dufay and his contemporaries downward into the secular fancies of people whose daily thought was influenced by the authority of the church.

Furthermore this method of turning part songs into solos survived until the era of the full fledged madrigal dramas of Vecchi in the latter part of the sixteenth century, and at what may be called the golden era of the frottola was generally and successfully applied to that species of composition. Whatever the troubadours and minnesingers may have done toward establishing a metrical melodic form of monophonic character was soon obliterated by the swift popularity of part singing and the immense vogue of the secular songs of the polyphonic composers. When the desire for the vocal solo made itself felt in the exquisitely sensuous life of medieval Italy, it found its only gratification in the easy art of adaptation. In such scenes as those described by Boccaccio and much later by Castiglione there was no incentive to artistic reform, no impulse to creative activity.

We find ourselves, then, equipped with these significant facts: first, that the composition of secular music in polyphonic forms was at least as old as the thirteenth century; that part singing was practised in Italy as far back as the fourteenth century; that songs for one voice were made with Italian texts at least as early as the time of Dante and Boccaccio; that the art of arranging polyphonic compositions as vocal solos by giving the secondary parts to the accompanying instrument was known in the time of Minuccio and Casella; that at the time of Poliziano's "Orfeo" the frottola was the reigning form of part song, and that then and for years afterward it was customary to arrange frottole as solos by giving the polyphony to the lute or other accompanying instrument.

It seems, then, that we shall not be far astray if we conclude that the solo parts of Poliziano's lyric drama consisted of music of the better frottola type and that the moving appeals of his hero were accompanied on a "lyre" of the period in precisely the same manner as frottole transformed into vocal solos were accompanied on the lute. For these reasons an example of the method of arranging a frottola for voice and lute will give us some idea of the character of the music sung by Baccio Ugolino in the "Orfeo." The examples here offered are those given in the great history of Ambros. The first is a fragment of a frottola (composed by Tromboncino) in its original shape. The second shows the same music as arranged for solo voice and lute by Franciscus Bossinensis as found in a collection published by Petrucci in 1509.
