With Romanticism, music changes its role: it is no longer a mere accompaniment of the message delivered in speech, it contains/renders a message of its own, "deeper" than the one delivered in words. It was Rousseau who first clearly articulated this expressive potential of music as such, when he claimed that, instead of merely imitating the affective features of verbal speech, music should be given the right to "speak for itself" - in contrast to the deceiving verbal speech, in music, it is, to paraphrase Lacan, the truth itself which speaks. As Schopenhauer put it, music directly enacts/renders the noumenal Will, while speech remains limited to the level of phenomenal representation. Music is the substance which renders the true heart of the subject, which is what Hegel called the "Night of the World," the abyss of radical negativity: music becomes the bearer of the true message beyond words with the shift from the Enlightenment subject of rational logos to the Romantic subject of the "night of the world," i.e., with the shift of the metaphor for the kernel of the subject from Day to Night. Here we encounter the Uncanny: no longer the external transcendence, but, following Kant's transcendental turn, the excess of the Night in the very heart of the subject (the dimension of the Undead), what Tomlison called the "internal otherworldliness that marks the Kantian subject." What music renders is no longer the "semantics of the soul," but the underlying "noumenal" flux of jouissance beyond the linguistic meaningfulness. This noumenal is radically different from the pre-Kantian transcendent divine Truth: it is the inaccessible excess which forms the very core of the subject.- Slavoj Zizek, "Why is Wagner Worth Saving?"
