News Finding: 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.
Paper Finding: As the entrainment mechanism occurs for a wide range of acoustic stimuli, we find it unlikely to be following beat or meter in music: such clear groupings do not exist in other stimulus types.

  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.
Paper Context: This methodological choice allows us to study the rate of the music without delving into the complexities of beat and meter, which can shift nonmonotonically with increasing overall rate (i.e., faster notes are often arranged into larger groupings). As the entrainment mechanism occurs for a wide range of acoustic stimuli, we find it unlikely to be following beat or meter in music: such clear groupings do not exist in other stimulus types. We demonstrate that cortical oscillatory activity in both low (<8 Hz) and high (15-30 Hz) frequencies is tightly coupled to behavioral performance in musical listening, in a bidirectional manner.
