There have, however, been few attempts to specify this power empirically and to provide theoretically grounded accounts of music's structuring properties in everyday experience. Music in Everyday Life uses a series of ethnographic studies - an aerobics class, karaoke evenings, music therapy sessions and the use of background music in the retail sector - as well as in-depth interviews to show how music is a constitutive feature of human agency. Drawing together concepts from psychology, sociology and socio-linguistics it develops a theory of music's active role in the construction of personal and social life and highlights the aesthetic dimension of social order and organisation in late modern societies.
