Acoustic and Psycho Physiological Mechanismof Choral Singing and Its Influence on Methods of Vocal-Choral Work
The article deals with the acoustic and psycho physiological mechanism of choral singing as factors which specify a choirmaster work in singing voices development. Some ensemble characteristics such as evenness, tenderness and homogeneous sounding are developed successfully in choristers' voices, but at the same time voice intensity, sonorousness and timber identity require specific choral teaching techniques. One of them is the taskoriented influence of choral sonority on a singer's individual phonation. This method is based on acoustic-psycho physiological phenomenon of voice cotune in a choir. The author notes that the choristers sing in conditions of constant acoustic background and as the result they lose their auditory selfcontrol. It leads to forced sounding of their voices therefore choristers should be trained to the means of nonauditory vocal timbreforming selfcontrol with the help of resonator-vibratory sensation. Choirmaster's competence of objective mechanism of cosinging makes it possible to reach high-quality sounding both the whole choir and each chorister's voice.
