In the analysis of rhythms - both biological and social - Lefebvre shows the interrelation of space and time in the understanding of everyday life. He moves between discussions of music, the commodity, measurement, the media and the city. In doing so he shows how a non-linear conception of time and history balanced his famous rethinking of the question of space. This volume also includes his earlier essays on "The Rhythmanalytical Project" and "Attempt at the Rhythmanalysis of Mediterranean Towns".
