News Finding: It turns out, the answer has a lot to do with timing.
Paper Finding: Our findings provide evidence that the role of beta in temporal predictions scales to the complex hierarchical rhythms in natural music and enhances processing of musical content.
News Context: How brain waves entrain to music
  
  This image, taken from an MEG reading, shows a musicianaEUR(tm)s brain more strongly entraining to BeethovenaEUR(tm)s unhurried Sonata No. It turns out, the answer has a lot to do with timing. The work also reveals why your musician friends are sometimes more tolerant of really boring music.
Paper Context: This suggests a bidirectional relationship between behavior and cortical entrainment, a phenomenon that has not previously been reported. Our findings provide evidence that the role of beta in temporal predictions scales to the complex hierarchical rhythms in natural music and enhances processing of musical content. This study builds on important findings on brainstem plasticity and represents a compelling demonstration that cortical neural entrainment is tightly coupled to both musical training and task performance, further supporting a role for cortical oscillatory activity in music perception and cognition.
