Chapter 1: Music Representations

Musical information can be represented in many different ways. Chapter 1 of [Müller, FMP, Springer 2015] covers three widely used music representations: sheet music, symbolic, and audio representations. In particular, it discusses musical and acoustic properties of audio signals including aspects such as frequency, pitch, dynamics, and timbre.
