ENThe article deals with the ways of application of teacher - multi-instrumentalist’s skills in music schools. The authors established the theoretical background of the problem in a previously published article. The current publication presents the data of the empirical research obtained by interviewing the experienced instrument teachers. The main research questions were: how much the competencies of multi-instrumentalists are significant for instrument teachers and how they influence the educational process. The research results confirmed earlier theoretical presumptions: the interviewees emphasized the advantages of multi-instrumentalists’ skills in seeking the job, conducting different ensembles, applying knowledge of musical instruments, the capability of arranging/composing music, etc. Keywords: multi-instrumentalist, music, education, competencies.
