The first sound studies book to explore the topic, Humming offers a unique and original examination of the polarising categories of hums, from hums that are performed only to oneself, that are exercised in religious practice, that claim healing, and that resonate with our bodies, to hums that can drive people to madness, that emanate from cities and towns, and that resound in the universe. By acknowledging the quirkiness of hums within the established discourse in sound studies, Humming takes a truly interdisciplinary view on this familiar yet less-trodden sonic concept in sound studies.
