The article deals with the polypedagogical principle of Antonio Salieri's education in the context of the modern understanding of the polypedagogical reality, its phenomenality, and its unique features. The author examines modern trends in the formation of polypedagogical reality, the point of view of scientists on scientific approaches to the description of pedagogical reality. In the context of the works of representatives of artistic pedagogy, the polypedagogical principle in the teaching activity of Antonio Salieri is analyzed. It provided for the ability of one teacher to teach students to play an instrument, vocals, composition, solfeggio, harmony, instrumentation, music theory, polyphony, heterophony, homophony, the basics of counterpoint, and conducting. In the modern plane of «polypedagogical interaction» (work with a student group of several teachers), the main problems for musicians arise when several teachers work with groups (with a choir or an orchestra, where students of the first and second levels of higher education are trained). Such a situation simply cannot pass without a certain number of socio-psychological dilemmas - the problem of the psychological compatibility of teachers (individual-personal, psychophysiological, didactic), the problem of the compatibility of the technologies of these teachers and their teaching styles, the issue of the interaction of the leaders of educational groups with their participants and among themselves. The article shows optimal ways that require the teacher's moral responsibility and moral readiness for "subject-subject" and "subject-object-subject" interactions in large groups. In the context of dyadic and frontal relations between the teacher and students, the author proved that Antonio Salieri, who was uniquely able to coordinate and establish positive relations with the students who studied under him, quickly and simply gained authority, caused sympathy, sincere love among the students, the desire to be like him, to consider him a role model.
