This study seeks correlations between social variables and linguistic variables, including the following ten speech patterns: repetitiveness, long-windedness, drawl, charm and variability, amount of pausing, sharing of air time, tension, noisy qualities, breath control, and forcefulness. Many associations are discussed, particularly those involving societal complexity, sex roles, and singing and dancing.

This chapter explores the relationship between cultural complexity and song. Several measures of cultural complexity are correlated with different aspects of singing. All hypotheses are supported.

This chapter examines the relationship between social cohesion (measured using variables like subsistence type, stable work teams, and settlement patterns) and musical cohesion. All hypotheses are supported.

This chapter suggests that dance styles reflect cultural traits. The authors hypothesize that certain aspects of cultural complexity predict several types of dance movement. Hypotheses are supported.

A large-scale comparative study of folk songs around the world employing systematic measures (cantometrics). The aim was not just to describe variation but to test hypotheses about the relationships between song style and societal structures. Dance was also considered.
