This article sketches a new image of musical works, situated beyond the «work concept», critically rethinking existing music ontologies, and grounded on Gilles Deleuze’s central ontological commitments. After situating the problem, the paper discusses current issues in music ontology, explores specific Deleuzian and Deleuzo-Guattarian ontological concepts, and argues for a new image of musical works, which are more aptly described as assemblages, as highly complex, historically constructed multiplicities defined by virtual structures, intensive processes, and actual things.
