This paper presents the results of a Participatory Action Research, whose main objective was to validate a pedagogical intervention characterized by adopting an inquiry-based learning methodology (IBL), and the paradigm of Practice as Research focused on musical performativity. This intervention sought to foster autonomy, the relationship between theory and practice, and the development of critical reflexive skills in professional music students. The co-participants (12 students in the first cycle and 9 in the second) belonged to university training programs in vocal and instrumental interpretation, composition, and music pedagogy at different levels. In the intervention cycles, students were able to organize themselves collaboratively to achieve the learning objectives and research products designed in the intervention. During the process, they redefined research as a tool for professional development in their discipline. This empowered the participants, as they became aware that they themselves could build knowledge in their field. The intervention was validated, and the results highlight the potential of inquiry activities focused on musical performativity and Practice as Research in the context of higher music education, playing an integrating role in the construction of knowledge by and for practitioners.
