This chapter focuses on the methodological challenges and practical implications of the experimental ontology of music. It offers an overview of the existing research, primarily focusing on how people judge whether two musical performances are of one and the same or two distinct musical works, followed by a discussion of the current methodological debates in this field and, finally, an exploration of its potential legal implications.

In two experiments (N=888), we explore to what extent the folk concept of art is compatible with the leading philosophical definitions of art, and whether it is an essentialist or a non-essentialist concept. We manipulate three factors: whether an object is created intentionally, whether it has aesthetic value, and whether it is institutionally recognized. In addition, we also manipulate the artistic domain (visual art or music). The results suggest that none of the three properties is seen by the folk as (...) necessary for an object to be considered art, which suggests that the folk concept of art might be a cluster concept.
