Another nice passage from Benson, as found in, The Improvisation of Musical Dialogue:
“So what results from the improvisatory movement of composition and performance? From musical energia grows an ergon—but an ergon that still remains within the play of musical energia, and from which it cannot be disconnected. Indeed, we might more properly say that this ergon exists as energia. Thus, improvisation provides a way of conceptualizing music that does not force us to choose between defining music as either ergon or energia. Music that is improvised endures and is yet transitory. Being transitory, its existence is very much genetic, historical, changing: but, in that it likewise endures, it has a continuing identity” (p. 125).
So many nice theological parallels come to mind! I also noticed that Benson has a nice article on Jean-Luc Marion on one of my favorite blogs, TheoPhenomenon.
