At the beginning of the research, an extensive review of sources was made to explore changes in rhythms in the urban context. The sources focused on (1) understanding the types of rhythms people perform in daily, weekly and yearly cycles and how these take place in space and time; (2) understanding the urban practices and the interactions they enable; (3) visualising rhythms in charts and maps which indicate both spaces and times. As a result of this theory review, the concept of spheres was formulated.
