I've been pondering the purpose of vocals in the death and black metal genres lately, and found more questions than answers. Nietzsche describes music as the ultimate representation of the will because it is a direct link between sensual perception and the will of the artist. Modern music attempts to adopt the mantle of a poetic artform by using a lyrical focus from which the listener can construct a visualization of the artist's will. Metal obviously de-emphasizes a central vocal melody, but the best metal often carries with it in-depth lyrics that enhance, or at best narrate, the representation of will found in the song. Do you think that metal thus relies on poetry to construct an image through its music? If it does, then it does not conform to Nietzsche's definition of absolute music, which states that absolute music appeals completely to the senses. I'm not saying that it's lack of acheiving this state degrades the quality of metal at all. On the contrary, many a poem can be inspiring in the most profound ways; however, for a form of art that reaches towards not necessarily classical emulation, but the same will that fueled the movement of classical composers, you would wonder if any artists would forego lyrics or vocals in order to project their will in a completely abstract manner. Thoughts? Corrections? Suggestions?
