Cantometrics
Cantometrics ("song measurements") is a method developed by Alan Lomax and a team of researchers for relating elements of the world's traditional vocal music (or folk songs) to features of social organization as defined via George Murdock's Human Relations Area Files, resulting in a taxonomy of expressive human communications style. Lomax defined Cantometrics as the study of singing as normative expressive behavior and maintained that Cantometrics reveals folk performance style to be a "systems-maintaining framework" which models key patterns of co-action in everyday life.
