In this framework, Clifton finds that there are two things that separate music from non-music: (1) musical meaning is presentative, and (2) music and non-music are distinguished in the idea of personal involvement. "It is the notion of personal involvement which lends significance to the word "ordered" in this definition of music" . This is not to be understood, however, as a sanctification of extreme relativism, since "it is precisely the 'subjective' aspect of experience which lured many writers earlier in this century down the path of sheer opinion-mongering. Later on this trend was reversed by a renewed interest in 'objective,' scientific, or otherwise non-introspective musical analysis. But we have good reason to believe that a musical experience is not a purely private thing, like seeing pink elephants, and that reporting about such an experience need not be subjective in the sense of it being a mere matter of opinion" .
