Dionysian, Art, Communication

In Birth of Tragedy, Nietzsche shows that all Art is genetically Dionysian, i. e. that dithyrambic Music inspires Dancing, which releases all the symbolic powers, including the Apollinian ones.  At the same, that demonstration implies that all Art is categorially Dionysian, as well.  For, to characterize anything as 'symbolic' is to classify it as a 'language', and, hence, as a medium of Communication.  Now, Communication unites discrete individuals, and, so, is a Dionysian activity in Nietzsche's system.  Thus, if all the Arts are symbolic, they are all media of Communication, and, hence, are all species of Dionysian activity.
