I’ll let you read the article, but basically:
- Your brain waves sync up with the music you are listening to;
- Musicians' brains are better at entraining to music—they can make sense of slower tempos better than non-musicians; and
- Your unconscious brain cares more if low notes are off tempo than high ones.
Of course, the entrainment study only used classical music; I wonder how it would be different with other types of music?
