This study examines theoretical principles and models of music education to promote interpersonal and social relations. It focuses on the primary and secondary stages of education in Spain. To this end, relevant national and international figures in education, music or critical thinking were consulted. Their responses to the consultation were treated qualitatively. The results highlight the need to promote participatory activity and to design alternative proposals for music learning that invite the student to gain positive musical experiences. This will help to recognise different musical identities, promote intercultural musical diversity and encourage positive coexistence in and beyond the music classroom.
