I have been working on a theory of aesthetics and wished to have the input of someone more well versed in the philosophical literature. I have mostly centered upon music, as in: what makes one form of music, e.g. Classical, superior than another, e.g. Pop? Using Nietzsche's idea of genealogy, I determined that Rock and Roll could never be truly great art because of its development from slavery, much as Nietzsche attacked the Christian religion due to its association as a slave religion. The main quality that defines great art, I argue, is nobility. And this is a quality which servitude, or a spirit of art arising from servitude, cannot comprehend. Also, would it be possible to recommend reading that might aid me? Currently I am reading Hegel's Introductory Lectures in Aesthetics, and Kant's Critique of Judgment.
