  One worry about platonism with regard to music runs as follows: if a sound, and the hearing of a sound, are spatiotemporal events, and if a musical work is an abstract type that has no spatiotemporal location and that exists independently of particular performances of it, how could it be literally true to say that a musical work has such-and-such sounds? Do platonists about musical works have to accept the conclusion that musical works are, strictly speaking, inaudible (Davies 2009b)? Another worry concerns performances and their relation to the abstract objects of which they are a performance: if a musical work is a fully determinate abstract object, how could an interpretative performance of it be necessary to its appreciation (Predelli 1995, 2001)?
