Music as Biology

Music as Biology: The Tones We Like and Why explores the biological basis of musical tonality and listening preferences. Dale Purves examines how subjective reactions to tone combinations evolved from the behavioral advantages of recognizing human vocalizations.

The volume addresses fundamental musical questions that conventional music theory leaves unanswered. These include why human cultures rely on a tiny fraction of possible scales, why listeners perceive specific tone combinations as consonant or dissonant, and why major and minor scales evoke different emotional states.

Purves demonstrates that musical intervals share strong acoustic similarities with vocal sounds, framing musicality as an evolved biological phenomenon accessible to scientists and educated readers alike.
