My chapter in the Oxford Handbook of Western Music and Philosophy has just appeared.

This large book project is now out and my contribution forms chapter 7 and covers music and philosophy in the Middle Ages. OUP hasn’t given me any sort of access that I can post here, sadly, so I hope most of you have institutional access.
In short, the chapter outlines some of the varied relationships between music and philosophy in the Middle Ages. As one of the disciplines of the mathematical quadrivium, musica concerns issues of acoustics but the notation and ontology of music additionally relate to grammar, logic, and rhetoric. Furthermore, music is related to the boundaries between human and non-human animals and overlaps with, while not being completely subsumed by, sonic practices, something I cover in a subsection called ‘Unsound Studies’, which encapsulates some of my problems with Sound Studies’s treatment of historical materials!
Medieval music was also implicated in writings on ethics, which give evidence of music’s role in gendered and political identity formation, which I treat here a little bit. Finally, the chapter considers what sort of knowledge musical knowledge was in the Middle Ages and why modern thinking might struggle with various aspects of music’s relation to philosophy in this period.
