In this thesis, we talk about music therapy as a concept, about its influence on the individual and for which goals we use it. The history of music therapy and the methods and approaches we can use are also mentioned. Some of the better-known improvisational models of music therapy are the Orff method and the Nordoff-Robinson method. In the research part of the paper, the widespread use of music therapy in classroom teaching was investigated using a google survey. The objectives of the survey were explained and the research tasks and hypotheses were described in detail. The purpose of the research questions was to determine how many years the respondent has been employed, in which class department he teaches, in what environment he teaches, how often he uses the voice therapy method, whether he knows what it is and how to use it, and whether he wants to be educated about music therapy. From the research, we conclude that most teachers use music therapy in the Musical Culture class, and they use Orff's instruments. The paper ends with the final results of the research and the analyzed questionnaire for classroom teachers.
