I will argue that there are (at least) two species of musical silence, which cannot be distinguished by attending to how these silences sound. I term these two kinds of musical silence ‘capacious’ and ‘opaque’. Both capacious and opaque musical silences might occur in the midst of the ongoing production of sound or might exist in the complete absence of sound. Both kinds of silence can, in certain conditions, be sonically identical, but both are always received by the listening ear (...) in importantly different ways. I will discuss our ability to distinguish between these silences, even when they ‘sound’ the same. I will argue that the accounts of musical silence and silent music offered by (among others) Levinson, Kania, and Davies are vitiated by their failure to distinguish between these kinds of musical silence. I distinguish these kinds of silence by the kinds of listening activity associated with them, and the ideal structure of such listening practices. (shrink)
