Classification and Phylogenetic Analysis of African Ternary Rhythm Timelines
Year: 2003 Authors: Godfried Toussaint
Core claim
The ten bell patterns form one combinatorial class and each can be derived from one of two canonical patterns by at most five swaps, with no additional ancestral rhythms suggested.
