The voice is a wind instrument, a component of music that is created by the vocal folds of a person. The human voice can be used in different ways in music, for example singing. A vocalist is a musician who sings, and a singer is a person who only sings.
The human voice as a means of producing musical sound
Human beings have long used their own voice to produce music.
In each culture, the voice is handled differently according to its own musical style. Each human voice is different and therefore classification is not always easy. In the West, human voices are classified based on two concepts: tessitura and timbre.
Tessitura is the range of notes in which a voice is most comfortably sung. Timbre, as mentioned when dealing with the qualities of sound, is the special characteristic that distinguishes one voice from another. Generally, a high-pitched voice has a thin or clear timbre, while a low-pitched voice will have a thick or dark timbre. As stated before, each voice is different and there may be exceptions to the pitch-timbre correspondence. Although there are more detailed classifications used by specialists, the general classification of human voices is presented below.
In the male voice, the clear voices are made up of: the voices of Tenor and Countertenor, and the dark ones by the voices of: Baritone, Bass. However, here are some exceptions, being able to find tenors with a darker timbre, such as the Dramatic Tenor or the Lyrical - Spinto, which would also form part of the dark voices.
In the case of female voices, the clear voice is constituted by the Soprano, also finding, as in the male case, exceptions in terms of certain sub-classifications, (Dramatic Soprano - Lyric Soprano-Spinto)
And the dark voices are integrated by the strings of: Mezzosoprano, Contralto and Guttural. The latter being extremely difficult to find.
It is important to mention that the voice is an instrument of birth. Therefore, each person already has a certain type of voice and what is done is to work with it. The types of voice are decisive for the characters in the opera. However, a singer can only sing representing the character that is in accordance with the texture and type of his voice.
In the case of choirs, only four voices are used: soprano, alto, tenor and bass; while the intermediate voices are represented with the other two.
The voice is the sound produced by the human speech apparatus. The conscious emission of sounds produced using the vocal apparatus is known as singing. Singing plays an important role in the art of music, because it is the only musical instrument capable of integrating words into the musical line.
The vocal sound is produced in a combined physical action. The parts are the support, the combined function of mucus, vocal cords and muscles (messa di voce) and of the resonance and suppression of the harmonics of the sound emitted from the larynx to the vocal tract (mouth, head).
The spectrum of harmonics has to be with the other timbre. It is individual in each person. In singing pedagogy, the process of awakening certain harmonics to make the voice bright is commonly called resonance. However, of the initial sound from the larynx, only 20% is actually emitted as a vocal sound; the rest is suppressed by the vocal tract. Therefore it is more correct to speak of partial filtration of the initial sound. Although the bone formation of each person is predefined, the correct way of emitting the sound to the vocal tract can be learned through constant training. It turns out that the voices perceived as prominent and bright are those with a strong formant ratio between 2,800 Hz and 3,200 Hz.
