The analytical circle includes a system ("text", "subtext", "over text", "context" of a musical work) which, in the author's opinion, can provide a technological breakthrough in the process of preparing performing musicians. Defi nitions of the definitions "text", "subtext", "over text" and "context" are given as a combination of the multidimensional space of a musical work ("4D").

It focuses on the fact that it is this technological approach that can contribute to the discovery of new perspectives in the pedagogy of musical performance.
