IMPROVISATIONAL ORCHESTRA AS AN ACTUAL PHENOMENON OF MODERN PROFESSIONAL MUSIC
The purpose of the work is to identify the creative methods on which the artistic and performing practice of improvisational orchestras is based. The scientific novelty of the research consists in introducing the concept of an improvisational orchestra into an art history discourse. The methodology is based on the analytical method applied to the creative practice of improvisational orchestras, as well as the source study and historiographical approaches, which made it possible to build a historical retrospective of this phenomenon. Conclusions. The creative activity of improvisational orchestras is a historically established, widespread area of modern musical creativity that combines the style of jazz and academic traditions. Their creative activity is regulated by a communicative link between the conductor and the orchestra, based on a closed language-sign system.
