Abstract: | In transposing the discussion of L.S. Vygotsky’s ideas to the cross-cultural area of science, the authors summarize the contexts and positions regarding the contribution of the Russian psychological school to the substantiation of musical therapeutic theory and practice. The analysis by Dr. Mastnak of European and American academic periodicals in psychology and music therapy showed that Western science does not have access to all of the content and achievements of Russian and Russian-language psychology. Reading Vygotsky’s works from a musical therapeutic perspective and, in addition, in a cross-cultural interpretation, the authors discuss the abundance of the psychological scientist’s methodological ideas that could provide a theoretical substantiation of effective music therapy. |
