This chapter examines the temporal process of the principal musical acts of the Anti-Atlas, which unfold in musical suites through extended periods of time, often over several hours or days. It shows what the temporal process and its metamorphoses have to do with the main plants of this region, the barley and the date palm, and pursues the following questions with reference to botany: how do the social actors construct the temporal process through performance? What are the key moments and how do the performers conceive the spatial orientation of this development? What are the components involved and how are they articulated? What concepts are related to the musical acts and what do they say about temporality? It is argued that analyzing musical rhythm of such rural areas requires an approach that takes full ethnographic account of the agricultural environment and practices.
