Part of this "disconnect" is because OWL describes an open world ontology. An Ontology has little or nothing to do with a program, other than a program can manipulate an ontology.

Until it's being played, it's just potential relationships among notes manifested as sounds. When it's being played, some of actual relationships will be relevant to you, the listener. Some won't be relevant to the listener.
