In his book, “Observations on the Florid Song,” Tosi has given a great deal of information regarding the methods of vocal training used during his day. The book is divided into three parts and consists of instructions to teachers, pupils and singers.
Tosi was a singer and composer, as well as, a teacher. His voice was a beautiful artificial soprano, which had been trained to a high state of perfection.
He sang with a great deal of emotional expression and his artistry was held in high esteem by the great singers of his time. They considered it a great privilege when they were given the opportunity of hearing him sing.
He was a great lover of his art and had the highest respect for those who distinguished themselves in music. On the other hand, he was very critical and outspoken toward all who abused or degraded the profession. Tosi spent a great deal of his life travelling. He made friends readily and some of his best ones were among the nobility. At one time he lived in England and became a leading figure in the musical circles of that country.
That Tosi considered the teaching of singing a serious undertaking is seen by the following quotations:
But above all, let the teacher hear with a disinterested ear whether the person desirous to learn hath a voice and a disposition, that he may not be obliged to give strict account to God, of the parent’s money ill spent, and the injury done to the child, by the irreparable loss of time.
Again warns the teacher:
From the first lesson to the last let the master remember, that he is answerable for any omission in his instructions and for the errors he did not correct.
Tosi also maintained that the pupils were responsible to the teacher in many ways. He felt that if the teacher was instrumental in the success of a singer, he should also be entitled to a share of the fortune made by the singer.
Tosi’s system of voice culture was one of progressive development from the first lesson to the completion of the course. The first few months of study were confined to the middle part of the voice. Single tone exercises were practiced until the student could sing with a clear steady tone, for the full duration of the breath, in varying degrees of dynamics, all the intervals of the middle octave. Short scale exercises for acquiring agility were then added. They consisted of just a few tones which were sung at a slow tempo. As the voice gained in flexibility, the speed was increased. Upon mastering the short scale exercises the messa di voce (swelling and diminishing a tone) was taken up. It was used to develop control and power of voice. Tosi considered the messa di voce of the greatest importance.
After the middle octave was firmly established, the next step was to extend the range of the voice in both directions. To develop the high tones, Tosi used scale passages on the different vowel sounds. The student was cautioned to practice softly, with light quality of tone. The scale exercises would extend three or four tones above the middle octave. After these could be sung with facility, the messa di voce was practiced on the upper tones. Tosi found that the combined practice of the messa di voce and the scale exercises were especially beneficial in extending the range of the voice and in firming the upper tones. He used this method in his teaching, adding note by note, until the upper limit of the voice was reached. Scale exercises of increasing difficulty practiced in varying degrees of dynamics were then added. The lower tones of the voice developed in the same manner.
At this stage of the training, the student took up the study of the appoggiatura, the shake, (trill) and divisions (runs). Tosi demanded musical perfection in preference to speed. He insisted that his pupils practice with this in mind. He would not tolerate a muddy shake or a slovenly executed division. Thus, the process of acquiring speed and agility required a great deal of patience and perseverance on on the part of the student and the master alike. Florid exercises were all practiced with a slow tempo, gradually increasing the speed as the voice acquired flexibility and freedom. Vowels were used, preference being given to the open ones. When the pupil was able to sound his vowels perfectly, the exercises were practiced with words and the building of a repertoire began in earnest.
Pure legato singing was emphasized by Tosi from the first lesson to the last. He never let his pupils become careless, or fall into slovenly habits of slurring their tones. They were taught how to sing with a steady flow of tone moving from one note to another, with perfect assurance and clear intonation. Tosi considered nasal and throaty production two of the worst defects of singing.
Some writers maintain that Tosi was the first voice teacher to refer to the registers of the voice. However, this is in error. If we refer back to Caccini, we find that he believed the voice to have two registers, which he called, “voce piena” (full voice) and “voce finta” (disguised voice). Tosi’s conception of the term register was not the same as that used during the present time which divides the voice into separate sections. The term as he used it had reference rather to a distinctive quality of tone. According to Tosi the term register was taken from the different stops of the organ and was used to describe various tone qualities produced by the voice. He believed the voice to have three registers, which he called “voce di petto” (chest register) and “voce di testa” which he describes as coming more from the throat than the breast. This would perhaps be the same as the middle register. He also mentions the falsetto (head register) which he claimed was formed entirely in the throat. Tosi used the term “feigned voice” for the falsetto. He believed that the falsetto could be developed and made a part of the voice so that the entire range of the voice was of consistent quality. In his teaching Tosi said very little about registers.
The terrible break in the voice that we hear so much about today, and which seems to be the main source of trouble in the development of an even scale, was given little thought by Tosi and his associates. The chief reason for this was that in their methods of teaching, the weak places in the voice were strengthened gradually and never reached the proportions of a break.
Tosi was considered an authority on voice culture by his contemporaries. Many of his pupils became teachers of voice. It may be for this reason that part of his book was written especially for the teacher.
