In the current study, however, they found that bass-heavy music was more successful at locking the brain into the rhythm.
“There is mounting evidence supporting the hypothesis that selective synchronization of large pools of neurons of the brain to the beat frequency may support perception and movement to the musical beat.” They found that brain activity became synchronized with the frequency of the beat. The scientists played each participant rhythmic patterns, in either a high- or low-pitched tone, and recorded the electrical activity of the person’s brain using electroencephalography (EEG). These sounds are thought to be important in the urge to dance because, as the authors explain, “bass instruments are conventionally used as a rhythmic foundation, whereas high-pitched instruments carry the melodic content.” The scientists - from Western Sydney University’s MARCS Institute in Australia - were particularly interested in the way that our brains process low-frequency sounds.
