Lefebvre's book, 'Rhythmanalysis: Space, Time and Everyday Life' (1992/2004) has been a stimulating resource for thinking about everyday life, space and time. Upon reviewing the other theories on daily life, it is considered as an umbrella term embracing all these theories as well as bearing traces of each. The method of Rhythmanalysis, which is the main concept of this study, is not merely restricted to the way that Lefebvre put forward the theory. In this study, how this concept emerged and is handled will be analyzed in detail. Rhythmanalysis is a tool for recognizing and understanding everyday life and space, as well as finding traces that reveal the authenticity of spaces. How do rhythms shape the human experiences of time and space? How do rhythms penetrate everyday life and space? These are the main questions to be answered in the study. This study focuses on the emergence of Lefebvre's method of 'rhythmanalysis' and its use in different disciplines as a means of analyzing urban space. Daily life rhythms contain the most comprehensive data indicating the daily life of the citizens in the urban space. Within the scope of this study, the concept of rhythmanalysis, which Lefebvre defined theoretically, has been practically applied in İzmir Kıbrıs Şehitleri Street. The identity and unique characteristics of this street, its actors and components of everyday life have been defined by considering everyday life theories and applying this method.
