Volume 3: The Foundation Matrix Extended and Re-configured

In this book, the authors develop the theory of the tripartite matrix, consider music as a form of non-verbal communication as a sub-dimension of the matrix, and present empirical studies of the matrices of peoples in three societies in the Middle East. It aids in the project of group analysis.
