Abstract
I am generally unsympathetic to the project, pursued by many recent philosophers of music, of attempting to specify the identity conditions for musical works – of attempting to specify the conditions that something, typically a performance, must satisfy if it is to count as an instance of this or that work. Call this the identity-project. Elsewhere, I have suggested that any such project is fundamentally misconceived. Here, however, I want simply to explore a couple of the difficulties with which the identity-project is confronted, and to point out some of the costs that are likely to be incurred in trying to overcome them
