In the Master's thesis, during the 2021-2022 academic year, an intervention was carried out, in a public educational center, for children in 5th grade, to improve their self-esteem and non-verbal communica- tion of the group and thus increase their confidence through music therapy due to the emotional defi- ciencies that were observed in them.The results were positive since there was an improvement in the self-esteem of the group, which was reflected in the results of the Rosenberg Self-Esteem Scale and the academic results.The method that was carried out was Bruscia since the group was physically acti- ve with a need to be heard and express their emotions. In conclusion, the application of preventive music therapy in the group has benefited the attention to the educational needs of the students by offering them a space to express their emotions and make their observations of what they thought and felt in coherence with the action of the movement.The fact that it is a dynamic and active interven- tion has produced an improvement in care. In addition, body and emotional control have evolved along with expression, personal initiative, and creativity, aspects that have helped them in their academic per- formance.
