Bass instinct: low notes really do get people dancing, research finds

Neuroscientists show clubbers move more to very low frequencies, even though they are not consciously detectable

 

When it comes to getting into the groove on the dancefloor, it really is all about the bass, researchers have found.

Scientists say when very low frequency (VLF) sound was introduced during a live electronic music event, gig-goers moved more even though they could not hear the frequencies.

 

“This is real world – real electronic music dance concert – validation that the bass really does make people dance more, and this isn’t just something that comes from our conscious awareness,” said Dr Daniel Cameron, a neuroscientist and first author of the work from McMaster University in Canada.

Cameron and colleagues note that previous studies suggested music that induces dance has more low frequency sound, and that low pitches help people to move in time to music.

Writing in the journal Current Biology, the team report how they set up an electronic music concert by the Canadian duo Orphx at McMaster and asked attenders to wear motion-capture headbands before turning on and off specialised VLF speakers every 2.5 minutes during the 55-minute performance.

Results from 43 attenders who agreed to wear a headband revealed they moved 11.8% more, on average, when the VLF speakers were turned on. Cameron noted this meant people danced more vigorously, or with more exaggerated movements.

At the end of the concert, 51 attenders completed a questionnaire that asked whether they could feel the music in their body, and whether the bodily sensations affected their compulsion to move.

The results suggest the concertgoers experienced bodily sensations associated with the music, but that these feelings were not rated as stronger than at similar concerts – settings where VLF speakers are not typically used.

The team then conducted a further experiment in which 17 people were asked to distinguish between a pair of clips from the concert that were identical, and a pair that differed only by the presence or absence of the very low frequencies.

The results from 72 such trials revealed participants did no better than chance at telling the pairs apart.

Cameron said that backed up the conclusion that concert attenders were not consciously aware of any influence of the VLFs.
