Episode 5: Cross-culture variation in preferences for consonance, with Dan Shanahan and guest Josh McDermott

Music Theorist Daniel Shanahan recommends “Indifference to dissonance in native Amazonians reveals cultural variation in music perception” by Josh H. McDermott, Alan F. Schultz, Eduardo A. Undurraga, and Ricardo A. Godoy, published in Nature Letters in 2016. Dan and Finn interview Josh about the musical culture of the Tsimane people, adapting music cognition experiments for cross-cultural studies, and what the absence of preference for consonant intervals (over dissonant intervals) in the people of one culture means for theories of music cognition more broadly.
