Since the concert and performance activity represents a flexible and mobile phenomenon, with inexhaustible possibilities of responding to what is happening in reality, the problem of an in-depth analysis of the concert and performance activity foundations, both theoretical and practical ones, continues to be a relevant topic for researchers. This is what prompted this study to address and explore this issue. The purpose of this study is to reveal a general picture of the phenomenon that concert performance represents and how its content and functioning are directly influenced by its practical and theoretical components. The materials for studying the main theme include information that reveals the evolution of the concert and performance art, its continuous modernisation and broadening of its scope. The methods used to study theabove-mentioned object are system analysis, the principle of deriving categories and generalising the data obtained by creating a panoramic picture reflecting the volume and multi-component nature of the phenomenon under study as a holistic system. The result of the work performed is, on the one hand, to establish a set of the most important categories - the elements of theoretical and practical components of concert and performance activity and, on the other hand, to form a picture-panorama which gives a general idea of the issue, its content and the ways of its implementation in the life of society.
