For the normal average organ of hearing of a person, there are some limit (threshold) minimum values of the physical parameters of the sound field, at which there is still an auditory sensation. Such a threshold of audibility is the standardized sound intensity I0 = 10 … 12 W / m2 (close to the threshold of audibility at f = 1000 Hz in silence), as well as the corresponding sound pressure p0 = 2 * 10-5 Pa and sound energy density e03 * 10-15 J / m3. The hearing threshold is private dependent. Above the threshold of hearing is the hearing area. In fig. 1 shows a curve of the threshold of audibility. The upper threshold of audibility is also shown there, above which the destruction of the organ of hearing can occur – the pain threshold, which corresponds to pressure pmax = 150 … 200 Pa, which exceeds 107 times p0 = 2 * 10-5 Pa.

“The poet belongs to the form, and the content to the history and reality of his people” (Belinsky; compare Glinka: “The people compose music, we only arrange it”). Consequently, the artist’s task is to discover (rather than invention) the content and invention for him the form corresponding to him (expressing the form in a broad, philosophical sense).
Chernyshevsky argued that art is a weak semblance of life and that, for example, paintings depicting the sea are needed only by those who have not seen the real sea. But it seems that the old woman, who served as the original for the Rembrandt picture, did not attract such attention as this picture, and that the Continue reading
The voice that nature has endowed with man is capable of transmitting sounds not only in conversation and expression of emotions, but also when singing. The melody of the human voice is very rich, its palette is multicolored, and the pitch ranges are very individual. It is these criteria that allowed a person to define a separate genre of vocals in art.
The concept itself was defined and indicated in Latin (vocalis – “sounding”). A vocalist is a musician using his voice as an instrument. It can be low-pitched and singing uppercase notes. Bass or soprano, baritone or mezzo-soprano, viola or tenor are different types of singing voices. The category of vocalists includes not only singers of classical parties, but also performers of recitations and artistic recitation. Classical Continue reading
