Inclusion promotes equal opportunities, and aims to eliminate discrimination, by ensuring full access, participation, and representation for all individuals in society, with music playing a crucial role in addressing this global challenge, and fostering positive and inclusive change. The aim of this study is to identify perceptions of inclusive culture, policies, values, and practices in one specific inclusive choir in Spain. The sample consisted of 135 members, ranging from 18 to 79 years of age, of which 22.2% have recognised disabilities. All of them filled in the adapted Scale for the Assessment of Inclusion (SAI) form. The results show that, regardless of gender, age, and length of participation in the choir, their members share positive perceptions of the inclusiveness of its values, policies, practices, and culture. However, perceptions vary across the groups surveyed, and are generally more favourable among participants with a disability, those without a university education, or those aged 26 or over. It is found that people who participate in an inclusive choir, in which music is the mediating resource, perceive a high level of inclusion that allows them to feel they belong to a group where diversity, equality, and the promotion of people are respected. The findings are analysed, considering the importance of conducting multidimensional evaluations that include all members of an organisation.
