What is it that music actually does? What is that thing? I'm not entirely sure.
That music has physical qualities is unquestionable. A certain pitch can shatter glass. Low notes can cause the trunk of the car stopped next to you in traffic to shimmy and shake. Volume hurts our ears. Music, temporally bound, is material.
It affects the world around us. It engages the world around us. Sound waves travel through various substances...with greater or lesser ease depending on the substance, but it does travel. It moves.
But does it live, move, and have being?
Cosmic Christ – depth of reality. The resurrection of Christ is also of the body…exit wounds and all. So can the music that changes the shape of the world we live in not help us access the God who inhabits the world and heaven at the same time?
So often I read passages like the one above from Rock and Theology (an amazing blog, by the way) and I wonder what the hell we're all going on about. Music does not have agency in any conscious sense. It is substantive, of course, and could be analysed liturgically like any other liturgical object.
