The present work aims at providing an evaluation of musical formalism, as it was intended by Eduard Hanslick in his treatise On the Musically Beautiful, in the light of Ludwig Wittgenstein's remarks on aesthetics and music. After a short historical introduction concerning the origins of the concept of absolute music within the framework of Romantic aesthetics and the writings of authors such as Wilhelm Heinrich Wackenroder, E. T. A. Hoffmann and Arthur Schopenhauer, I suggest a definition of formalism on the (...) basis of Hanslick's account of music. I compare, then, Hanslick's view on music with Wittgenstein's reflections on music and aesthetics, referring to both Wittgenstein's early philosophy – especially to the Tractatus Logico-Philosophicus – and to the later writings – namely to the Philosophical Investigations and the Lectures on Aesthetics. The outcome of the comparison between Hanslick's and Wittgenstein's views on music leads the discussion to an evaluation of the plausibility of the dichotomy between formalism and anti-formalism, and to a reflection on the objects, aims and methods of aesthetics.
