Abstract
This article undertakes a comparison between Wittgenstein's philosophy of the early and late periods with the musical theories of Wittgenstein's contemporary, Heinrich Schenker, an influential Viennese theorist of tonality, as well as those of their contemporary Arnold Schoenberg. Schenker's reductive analytical procedure was designed to unveil fundamental and uniform ways in which all works of music function, unfolding a deep structure constituting their essence. Schoenberg deplored this line of thought, and for reasons strikingly parallel to those that led Wittgenstein back to what he called the ‘rough ground’ in his Philosophical Investigations. Ultimately, for Wittgenstein, the abstracted picture of the musical work as a platonic entity is nourished by grammatical conflations as well as by the Platonic and Cartesian legacies.
