Rhythm-Induced Altered States and the Evolution of Human Dance and Music

Rhythmic movement—such as dancing, chanting, and breathwork—is consistently linked to altered states of consciousness across human cultures, though systematic research is scarce. The authors propose four neurobiological mechanisms: modulation of autonomic activity through breathing changes, psychological amplification via expectation and fear, vestibular perturbations that distort proprioception and multisensory integration, and neural entrainment affecting brain oscillations and connectivity. They also review comparative evidence that rhythmic movement induces altered proprioception, arousal, and social attunement in nonhuman great apes, and suggest that rhythmic stereotypies (e.g., rocking, pacing) may be analogues of rhythm-based ASC inductors. These findings point to deep evolutionary roots for rhythm-induced state changes.
