What is grid mora?

Grid Mora is a term used in music theory and rhythm analysis. It refers to a system of organizing recurring rhythmic patterns in a linear grid format. This system is commonly used in traditional African music, particularly in Sub-Saharan Africa, where it is used to generate complex and intricate polyrhythms.

In Grid Mora, each beat in a rhythmic pattern is represented by a single cell in the grid, and each cell can either be filled or empty, indicating whether or not a sound is played on that beat. The cells are read horizontally from left to right, indicating the progression of time.

Grid Mora has been studied and analyzed by music theorists, ethnomusicologists, and computer scientists, who have developed algorithms and models to simulate and analyze its complex rhythms. It has also influenced contemporary Western music, particularly in the genres of jazz and electronic music, where it has been used to create complex and innovative rhythmic structures.
