Electronic music lovers know the drill. But how conscious is this reaction?
The researchers took a closer look at the relationship between bass frequencies and dance thanks to experiments conducted during real electronic music concerts.
Results published in the journal on Monday biology today, showed that participants danced nearly 12% more when researchers introduced a very low frequency bass. This was not heard by the dancers.
“We didn’t know when the change happened, but it was driving them,” McMaster University neuroscientist David Cameron, who led the study, told AFP.
The results confirm a special relationship between bass and dance that has never been scientifically proven.
heartbeat of music
A trained drummer, Cameron says that people who attend electronic music concerts “like to feel the bass very strong” and tend to play it very loud.
But they are not alone.
In many cultures and traditions around the world, “it tends to be the lower register instruments, such as bass guitars and bass drums, that give the musical pulse” and move humans.
“What we didn’t know is that we can actually get people to dance more on the bass?” Cameron said.
This experiment took place in a building known as LIVElab in Canada. concert hall and research institute.
About 60 out of 130 people who went to a concert by the electronic music duo Orphyx wore motion-sensing headbands to dance moves.
During the concert, the researchers intermittently turned on and off speakers that reproduced very low frequencies.
questionnaire filled out by concert– Visitors confirmed that no sound was detected. This allowed the researchers to isolate the influence of the bass and avoid other factors such as dancers responding to popular parts of the song.
Below level of consciousness
“I was impressed with the effect,” Cameron said.
His theory is that even if undetected, base stimulate sensory system in the body such as the skin vestibular system— more commonly known as the inner ear.
These systems are very closely related to the motor system that governs movement, but intuitively bypass the motor system. frontal lobe.
He compares it to how the body keeps its lungs breathing and heart beating.
“It’s below the level of consciousness.”
Cameron said the research team believes that stimulation of these systems “provides a little boost to the motor system, which adds a little energy and vitality to real-world movements.”
He hopes to test this hypothesis in future experiments.
Why humans dance remains a mystery.
“I’ve always been interested in rhythm, especially what rhythm is and what makes us want to move.” dance.
Most theories revolve around the idea of social cohesion.
“When you tune in to people, you tend to feel a little more connected with them afterwards,” Cameron said.
“By making music Being together can make us feel better together as a group, work better as a group, be more efficient, and be more peaceful. ”
