Electronic music lovers know the drill: when the DJ turns up the bass, the crowd goes and dances with great enthusiasm. But how long does this process last?
Researchers have looked closely at the relationship between bass frequencies and dance, thanks to an experiment conducted during a real electronic music concert.
The results, published Monday in the journal Modern life supportshowed that people danced about 12 percent more when the researchers produced a very low-pitched bass – one that the dancers couldn’t hear.
“They can’t tell when those changes happened, but it drives their movement,” said neuroscientist David Cameron of McMaster University, who led the study. teaching.
The results confirm the special relationship between bass and dance, which has not been scientifically proven.
The rhythm of the song
Cameron, a trained drummer, found that “people who go to electronic music concerts love it when they can feel the power of the bass” and turn up the volume.
But they are not alone.
In cultures and traditions around the world “it’s the low instruments like the keyboard or the bass drum, that give the pulse of the music” that moves people.
“What we don’t know is, can you make people dance more with the bass?” Cameron said.
The experiment was carried out in Canada, in a building called LIVElab, which served as a concert hall and a research laboratory.
About 60 of the 130 people who went to see the concert by Orphyx were equipped with video headsets to monitor their dance moves.
During the concert, the researchers turned on the low-frequency speakers that played the speech sounds.
A questionnaire filled out by concert-goers confirmed that the sound was undetectable. This allowed the researchers to isolate the effect of the bass and avoid other factors, such as the response of the dancers to a popular part of a song.
Below the level of knowledge
“I’m happy with the result,” Cameron said.
His theory is that although it is not known, the bass stimulates the sensory systems in the body, such as the skin and the vestibular system-known as the inner ear.
These systems are closely related to the motor system—relevant for movement—but in an intuitive way that bypasses the frontal cortex.
He compares the way the body controls the breath and the heart.
“It’s below the level of awareness.”
Cameron said the research team believes that the stimulation of these systems “makes your motor system a little bit stronger.
He hopes to prove this hypothesis in future experiments.
Why people dance is still a mystery.
“I’ve always been interested in music, and the thing about music that wants to move,” despite the lack of a dance routine.
Most of the theories are based on social theory.
“When you hang out with people, you feel like you’re going to hang out with them a little later. You’re fine later,” Cameron said.
“By making music together, we can feel better as a team, then we work better as a team, and we can be better, and we can when there is peace.”
