This chapter approaches two texts in detail, both of which explicitly focus on the relationship between music and philosophy: ‘L’Echo du sujet’ – a well-known essay from the early collection Typographies I (1979) which theorises a ‘catacoustic’ subject (rooted in a proto- or pre- subjective musico-rhythmic element) – and Le Chant des Muses (2005), transcribed from a talk aimed at teenagers given towards the end of his life. As well as critiquing the alignment of the maternal-feminine with the musical, the chapter probes at Lacoue-Labarthe’s construction of this essentially rhythmical/emotional – and constitutively nostalgic – subject and locates in this gesture his own autobiographical impulse. The chapter also develops from the thinking on tonality outlined with Nancy, to develop a critique of the assumed notion of the musical work: a static, total, bound and autonomous object which obscures its means of production and the labour required for its (re)production (regardless of whether it is actually performed, as such). Finally, in the way that Lacoue-Labarthe expressly puts this into relation to education, socialisation and environment, the chapter argues that there is an important political and ethical value to Lacoue-Labarthe’s conception of a ‘catacoustic’ subject.
