Structural-Functional Model of Musicians Performance Reliability in Concert And Stage Activity

The author of the article developed a structural-functional model of performance reliability of musicians in concert and stage activities and displayed it in a picture in its entirety. It is quite clear that the performance reliability of the performer is not innate, but formed by a property that provides favorable psychological conditions for the dominance of stimulating types of pop excitement ("excitement-elation" and "excitement in the image") over destructive ones ("excitement-fear", " excitement-panic" and "excitement-apathy"). Such dominance is also necessary for error-free sound realization of imaginatively created variable images of musical works using coordinated reproduction of performance skills. The components of performance reliability of musicians in concert and stage activities are determined and described by the author in accordance with their functional orientation. The author proves that the basis of this phenomenon consists of three interdependent macro-components — preparedness of the concert program, self-regulation of concert and stage activities, and interference resistance. Microcomponents of performance reliability of musicians in concert and stage activities are described taking into account the studied material. The preparedness of the concert program by musicians-performers depends on the quality of the interpretive model of musical works formed in the imagination, the perfection of the musician's technical equipment, the flexible ability to memorize material, information support and the automation of performance actions, the accuracy of muscle-force movements, their temporal relationship and sensory motor coordination. The functional orientation of the micro-components of self-regulation of concert and stage activity in the performance reliability of musicians is revealed, namely: self-control, self-evaluation, self-correction, attributes of control and their models. Four vectors of interference resistance of musicians-performers in concert and stage activities are described, where the first vector ensures the avoidance of the disorganizing influence of stressors on its course, the second - its leveling, the third - sensorimotor endurance of the excessive action of strong, sudden and long-lasting stressors, and the fourth - success resisting them. It has been proven that the resistance of musicians-performers in concert and stage activities depends on their general physiological stability, psychological stability, emotional stability, emotional-volitional stability and stress resistance
