To be a Teacher …

To be a Teacher …

On 31st of August, 2021 in Bulgaria the great opera star Sonya Yoncheva together with Maestro Placido Domingo performed an unforgettable concert.  The event took place in Sofia, in front of the Alexander Nevsky Church.    Over 6,000 spectators had the opportunity to enjoy the highest opera art. 

I had the happy opportunity given to me personally by Sonya Yoncheva to be on the front line, and to experience some of the strongest emotions in my life.  It is no secret that I am Sonya’s first vocal teacher.  Together we took the first steps on her path as a singer.

  Today Sonya Yoncheva is one of the best singers in the world of the opera.  But she is an extremely noble person and never forgets her teachers.  Sonia gave me an invaluable moment that stays in my heart forever by introducing me to Maestro Placido Domingo as “My Professoressa “. 

No one can imagine the excitement I experienced when Maestro Domingo said that our vocal work with Sonia was perfectly done.  This is a moment that happens once in a lifetime and stays in the heart forever.

Anatomy of the voice

In the classical singing practice and theory stand hand by hand. Before we advance to the vocalization process itself, we should have the common acknowledgment of the anatomical structure of our voice, and how the vocal system is working. The organs, which take part in the process can be differed in 3 main roups:

The first group

Are the organs, that are connected with the singing, include those parts of the body, that provide it with air. The air is the media which is transforming in the voice. This group includes lungs, bronchi, trachea, and breathing muscularity.
I want you to pay attention of the breathing muscularity, because it will take an active part during the working process. They are in two types:

Inspirational muscularity – inspirational. Here, the diaphragm
has the main function. It is a flat muscle in the shape of an umbrella.
When inhaling, it goes down and gets flatter. Thus, it gets to be as if a charger that takes the air into the lungs. During exhalation, the diaphragm rises above and eminds
as a cupola. Other muscles of this group are the ones connected to the
ribs and the collar bones. 75% of the inhalation process in performed by
the diaphragm, the remaining 25% are committed by the other muscles.


The exhalation muscularity – expiration. It is the most important one in the singing process, and during the whole of our lives, we train these muscles, in order to sing beautifully and correctly. Those are four couples, which intertwine and shape the abdominal muscle waist-band. While singing, this waist-band has the most active, and important work.

This is exactly why, during the lesson, I spare some time for a specialized training, which is training, developing, and sustaining the
elasticity power of the mentioned above waist-line.
When it is trained in a long period of time, it gets to be an abdominal press, which, with the power of our own will, and thought control, pushes the air above. I am always repeating to my students, that the abdominal press is the motor of the human voice.

The second group

Are the large group of organs, connected with the singing, are the ones, that sound the air. Here the larynx, the pharynx, tongue, nose, the cavities surrounding the nose and above it, take part too.

1. The Larynx converts the air into a primary sound. It is a vertical tube, compounded of nine cartilages. Inside in the thinest part of the larynx, there are the vocal cords situated, which fulfill the function of the voice generators inside the human body. The vocal cords have a delicate, and in the same time complex structure. Their muscle fibers are able to be reduced into three different directions.

They can vibrate throughout their whole length, or just in different
parts of theirs, thus making the phonation. The vocal cords should
be elastic and strong. Also their color resembles the ivory color.

2. Resonators.
This group includes the places through which the produced in the larynx primary voice passes. Here the sound resonates, and gets its final shape, power and tone quality/timbre. After this, it’s flies away in the outer space with unique color. The resonators of the human voice are: the highest part of the larynx, the oral cavity, the nose, and the surrounding nasal cavity, These organs form the resonator tube. Under the larynx important resonators are trachea and the chest.
In a conclusion, the process is as follows: the air flow is putting in motion the vocal cords. They tremble and produce the voice waves. The voice waves reach out the resonators, and in the acoustic rules, create the phenomenon “human voice”.

Third group

We reached the human voice most important organ – the brain. The singing itself, is a psychophysiological process. The vocalization is a product of a highly organized neural action.
The singing is a neurological program of a very strict consistency. All of the singing habits are formed by the will power, and in consequence they get automated. What is very important to be known is that, before singing, the idea of the voice should be conceived. Out of it, the brain starts commanding all the parts of the vocal apparatus in the reflex arc principle. In a consequence, the breathing, singing, the resonance of the voice and the opposite hearing connection are being accomplished.

Some historical facts of the
classical singing – part two

Lecture No4

Thanks to the art school in Florence, the aesthetically criterion of singing are being
developed: singing should be “beautiful, melodious, have wide cantilena, and clearly
pronounced text. These requirements reached their peak with composers such as Alessandro
Scarlatti (1660-1720), and Claudio Monteverdi (1567-1643). After then a headlong tendency
appeared, in which the vocal virtuosity was more significant, and the text was not so
important element in the song. As an example, in the Pergolesi (1710-1736) composer’s opera
“La Serva Padrona”, in which the important vocal element is the coloratura.
Nicola Porpora (1686-1768) – composer and teacher of singing in Neaples, whose most
famous singing students were the castrate: Farinelli, Kaffarelli and Porporino.

Farinelli can be considered as a first singer “superstar”.
Other students of Porpora were composers Johann
Adolf Hasse and Joseph Haydn. In Porpora’s school, apart
of the coloraturas in the scores, pointed out by the composer,
the singers have added more ornaments, passages, and
improvisations in order to demonstrate a brilliant technique.
Bologna was the other famous school of singing in the
17-18th century in Italy. The most famous names are Feri,
Tosi, and Konti. Pier Francesco Tosi (1653-1732) is a
remarkable singer, а castrate, and a famous vocal pedagogue,
teaching both: castrates and non castrates. He created
theoretical labor of correct and precise indications of the bel canto singers.

The Italian singing stile of the bel canto gets enormous growth in the 17th and 18th
century. It reached its peak in the castrato’s technique. The bel canto stile influenced on the
whole Europe.
Throughout the 17th, 18th and 19th century, chronologically in Europe araised some
important groundworks , prepared by important singing teachers:
• Jean-Baptist Berar ( 1710-1772). L’art du chant, Paris, publ. 1755.
• Bernardo Mengozzi (1758-1800). Methode du chant du Conservatoire de Music.
Paris, 1803.
• Alexis de Garaude (1779-1852). Methode de chant. Paris, 1809.
• Henric-Ferdinand Manschtein (1806-1872). Sisteme de la grande Methode de chant
de Bernacchi de Bologna, 1835.
• Gilbert-Luis Dupre (1806-1896). L’Arte del canto. Paris, 1846.
•Manuel Garcia-father (1775-1832) “Exercises
and Method of Singing with Accompaniment with the
Piano Forte”
•Manuel Garcia-son (1805-1906) “Traits complet
de l’art du chant. Paris”, 1855.
• Francesco Lamperti (1813-1892). L’Arte del
canto. Milano.

The authors which best describe the stile of bel canto singing are Manuel Garcia – father and son. Their works contain the best, most accurate,
detailed and fulfilled description on the ocal techniques.
They give the best base, upon which contemporary way of sing is build and refined.

Some historical facts of the
classical singing – part one

Lecture No3

Ever since at the farthest historical times, people have created songs. Some of these songs
were hymns glorifying the Gods, others were exposing the sorrow in times of funeral
ceremonies, and also there were songs, performed in holidays, or competitions too.

• In the Ancient Greece, singing was accompanied with an instrument: for example lire, trigonon, magadis and others.
Throughout the history, there are names of Ancient Greek singers memorized: Terpander, Stesichorus, and others.

Ever since at the farthest historical times, people have created songs. Some of these songs
were hymns glorifying the Gods, others were exposing the sorrow in times of funeral
ceremonies, and also there were songs, performed in holidays, or competitions too.

• There are historical facts about
the art of singing in the Ancient Rome as well.
Three types of a singing school can be found in that period:

  1. Vociferarril – teachers who used to work on the vocal diapason.
  2. Phonashi – teachers, working of the vocal resonance.
  3. Vocales – teachers of the vocal aesthetics.

• The historic data of the vocal art in the 15th century is not so rich, though it is known that
the singers used the imitation as a voice method. In that period mainly professional singing
was the church singing. The voice was required to be at the same time strong but tender, but
also light. Same time the voice making should be never from the nose or from the throat.

• Throughout the Renascence all of the arts in Italy have an active development. Each of us
are aware of the names of Dante, , Boccaccio, Petrarca, Leonardo da Vinci, Michelangelo,
Raffaello, Tiziano, and others as well. All of these authors have been influenced by the
Renaissance’ idea of humanism. Making thus a new way of understanding out of the
Ancient Greek’s ideas of art.
As a big cultural center in the 16th century used to occur in Florence. The music school
Camerata Florentine had been created. It was also known as Camerata de Bardi, that came
out of the name of Count de Bardi. In his home many artists usually gathered for discussing
the arts. The members of this activity were the poet and philosopher Ottavio Runaccini, the
composers Jacobo Peri, Giulio Caccini, Emilio de Cavalieri, Pietro Strozzi, and the lutenist
Vincenzo Galilei.
Most important of this period are:
⁃ The lyrics have been defined as main element in the vocal music, that confirms
the rhythm and melody.
⁃ The basic concepts is that the singer became a soloist and artist. The singer
can creates characters and roles on the stage and is not only a part of the music picture.

⁃ Leonardo da Vinci had represented the first model of the larynx.
⁃ Theoretical compositions about singing had been
created. An example is the book “Nuove Musiche” by Caccini. ‘‘
This book includes ancient madrigals and theory where Caccini
explains the rules of the singing. Some examples of his remarks are
“to be spoken musically”, “clear diction and correct intonation” and
Coloratura passages were used only where it is not being an obstacle
of the text’s pronunciation.
⁃ Some of the earliest Italian operas have been written.
Such as Jacolo Peri’s “Dafne”. “Eurodice” by Caccini, and others.
⁃ The concept of “Dramma per musica” has been
established. Thus had been called the operas in Florence at this
period of time.
Gradually, singing schools had been sprung up at Rome, Venice, Milan, and Naples. The art
of singing was developing very actively throughout the whole Italy at the end of 16th century,
and the beginning of 17th century.
