INFLUENCE OF CHORAL SINGING ON PSYCHO-EMOTIONAL STATE OF SINGERS

Previously we have described certain correlation between the protein composition of mixed saliva (PCMS) and human psycho-emotional state (PES). In this investigation, the analysis of PCMS was used to study the change of PES in the group in the process of creative activities, i.e. choral singing. During the experiment, three groups of singers performed different parts of songs in the course of their regular sessions. The saliva for the analysis was collected from the singers just before and after the choral singing. The results led to the following conclusions. The vast number of singers showed evidence of healthy mental state. During the experiment, in each of the three creative teams there was a relatively harmonious PES of the participants. Collective singing strengthened the positive PES of the most singers. In particular, after singing in the choir a few people were found to have changed their PES from depressive to normal. Also, the processing of the collected data showed that the analysis of the PCMS characteristics allows evaluating not only the direction of the PES change against the background of the creative process, but also the depth of the emotional experience. In conclusion, the results of the research provide an objective basis for the confirmation of the beneficial effects of choral singing on the psyche of the singers.
