Rhythmanalysis is a collection of essays by Marxist sociologist and philosopher Henri Lefebvre. The book outlines a method for analyzing the rhythms of urban spaces and the effects of those rhythms on the inhabitants of those spaces. It builds on his past work, with which he argued space is a production of social practices.The book is considered to be the fourth volume in his series Critique of Everyday Life. Published in 1992 after his death, Rhythmanalysis is the last book Lefebvre wrote.
