The document discusses several studies on the neurological responses to music. It summarizes that listening to expressive musical performances compared to mechanical performances activates reward pathways in the brain. Experienced listeners report more chills than inexperienced listeners. The mirror neuron system is also activated when listening to music, correlating with tempo fluctuations. Chills experienced while listening to music tend to cluster in certain parts and are highly reproducible, requiring intrinsic knowledge of the music.
