Do you recall reading about the dancing cockatoo Snowball with the head-banger technique? Snowball was a big hit for a while there. I think critter behavior is interesting even when it does not look like human behavior, but it seems that scientists can’t get enough of animals dancing like humans.

Here are two relevant Guardian reports — one on on sea lions and one on rats.

“Ronan the sea lion can still keep a beat after all these years. She can groove to rock and electronica. But the 15-year-old California sea lion’s talent shines most in bobbing to disco hits such as ‘Boogie Wonderland.

“ ‘She just nails that one,’ swaying her head in time to the tempo changes, said Peter Cook, a behavioral neuroscientist at New College of Florida who has spent a decade studying Ronan’s rhythmic abilities.

“Not many animals show a clear ability to identify and move to a beat aside from humans, parrots and some primates. But then there’s Ronan, a bright-eyed sea lion that has scientists rethinking the meaning of music.

“A former rescue sea lion, she burst to fame about a decade ago after scientists reported her musical skills. From age three, she has been a resident at the University of California, Santa Cruz’s Long Marine Laboratory, where researchers including Cook have tested and honed her ability to recognize rhythms. …

“What is particularly notable about Ronan is that she can learn to dance to a beat without learning to sing or talk musically.

“ ‘Scientists once believed that only animals who were vocal learners – like humans and parrots – could learn to find a beat,’ said Hugo Merchant, a researcher at Mexico’s Institute of Neurobiology, who was not involved in the Ronan research.

“But in the years since since Ronan came into the spotlight, questions emerged about whether she still had it. Was her past dancing a fluke? Was Ronan better than people at keeping a beat?

“To answer the challenge, Cook and colleagues devised a new study. … The result: Ronan still has it. She is back and better than ever. This time the researchers focused not on studio music but on percussion beats in a laboratory. They filmed Ronan bobbing her head as the drummer played three different tempos – 112, 120 and 128 beats per minute. Two of those beats Ronan had never been exposed to, allowing scientists to test her flexibility in recognizing new rhythms.

“And the researchers asked 10 college students to do the same, waving their forearm to changing beats. Ronan was the top diva.

“ ‘No human was better than Ronan at all the different ways we test quality of beat-keeping,’ said Cook, adding, ‘she’s much better than when she was a kid.’ “

Meanwhile, at the Guardian, Hannah Devlin writes that rats, too, “instinctively move in time to music. This ability was previously thought to be uniquely human and scientists say the discovery provides insights into the animal mind and the origins of music and dance.

“ ‘Rats displayed innate – that is, without any training or prior exposure to music – beat synchronization,’ said Dr Hirokazu Takahashi of the University of Tokyo.

“ ‘Music exerts a strong appeal to the brain and has profound effects on emotion and cognition,’ he added.

“While there have been previous demonstrations of animals dancing along to music – TikTok has a wealth of examples – the study is one of the first scientific investigations of the phenomenon.

“In the study, published in the journal Science Advances, 10 rats were fitted with wireless, miniature accelerometers to measure the slightest head movements. They were then played one-minute excerpts from Mozart’s Sonata for Two Pianos in D Major, at four different tempos: 75%, 100%, 200% and 400% of the original speed. Twenty human volunteers also participated.

“The scientists thought it possible that rats would prefer faster music as their bodies, including heartbeat, work at a faster pace. By contrast, the time constant of the brain is surprisingly similar across species.

“However, the results showed that both the rat and human participants had optimal beat synchronicity when the music was in the 120-140 beats per minute (bpm) range – close to the Mozart composition’s original 132bpm – suggesting we share a ‘sweet spot’ for hitting the beat. The team also found that rats and humans jerked their heads to the beat in a similar rhythm, and that the level of head jerking decreased the more that the music was sped up. …

“The team now plans to investigate how other musical properties such as melody and harmony relate to the dynamics of the brain.

“ ‘Also, as an engineer, I am interested in the use of music for a happy life,’ said Takahashi.”

Gotta love scientists! More on rats. More on Ronan.

Body Percussion

Leonardo Sandoval of Music From The Sole uses body percussion in dance.

Music is everywhere. You just have to listen for it. Children know. Most of them make music out of pots and pans before they can walk. I have pictures of my children and grandchildren sitting on the kitchen floor surrounded by everything they pulled out of the lower cupboards and getting ready to drum a joyful noise. You may have pictures like that, too.

Brenda Dixon-Gottschild at Dance Magazine writes about a kind of percussion that’s even more accessible than your pots and pans.

“Crash. Bump. Thump. Thwack. Whack. Knock. These are a few of the many synonyms of the word ‘percussion.’ All of them are appropriate when we look at the ways world cultures use the body as an instrument. …

“Clapping, stomping and striking body parts from head to feet in rhythmic or repetitive ways is a timeless means of human interchange, whether for pleasure, protest, entertainment, ritual, healing or survival. Hand- and body-clapping children’s games accompanied by sung or spoken rhymes are common around the world. … Enslaved Africans used body percussion as furtive communication — fearful of its messaging potential, plantation owners prohibited the use of drums, and to sabotage this taboo, the Black body became the drum.

“The juba dance, brought to the Americas in Middle Passage — the grueling sea journey of Africans captured from their homelands to live enslaved on foreign territories — was performed during plantation gatherings. In this dance of prowess, one person entered a circle of movers to exhibit their extraordinary variations on jig, hop and jump steps and was joined by a second dancer as the outer circle alternated rotating and remaining stationary. Pattin’ juba, the juba dance accompanied by clapping hands, chest and thighs, and the juba song — composed of short, rhymed verses that seemed like nonsense but carried double meanings — were ingenious later adjustments made to accompany the dance and send messages when drums were banned. Pattin’ juba further morphed into the hambone, a variation that centers on body percussion and is performed standing in place or seated, while retaining the original rhythm of the dance. …

“For Rennie Harris, legendary hip-hop concert dance choreographer and artistic director of Rennie Harris Puremovement and RHAW (Rennie Harris Awe-Inspiring Works), hambone was second-nature: ‘I don’t remember exactly when I learned or who taught me. In fact, I don’t even remember seeing it or being introduced to it — I just remember doing­ it,’ he says. ‘I was 7 or 8 years old; this was on Master Street in North Philadelphia. We used to sit on the stoops and challenge each other, doing the hambone, seeing who could do it the fastest, cleanest. It was a summer pastime. We sang the song, as well. Being older, I’d run into people who still do it, so it’s kind of interesting and cool. We’d add parts of it to dance steps. I didn’t learn the history of it, pattin’ juba, until later in life.’ …

“The basic hambone beat got a second life in the world of popular music. The 1950s R&B legend Bo Diddley made the five-accent hambone rhythm famous as the Bo Diddley Beat, a recurrent riff that has been appropriated by many white rock musicians.

“Tap dance, another style of body percussion, has impacted almost every culture. Using toes, heels and the full foot in rhythmic fashion goes beyond any one era or continent and includes traditions as diverse as African American buck dancing, Irish step dancing, English clogging and South Indian bharatanatyam.

“Beyond those traditional examples, the complex, polyrhythmic fusion of tap, combined with hambone-inspired body percussion, has proliferated with present-day artists across continents. The South African gumboot dance was transformed into a performance mode from its goldmine workforce origins, where it was created by Black miners as a sly replacement for conversation, since the white mine owners exacted harsh punishments for verbal communication among the workers.

“Other spinoffs include ensembles like Colombia’s Tekeyé; The Percussion Show, from Egypt; and the U.S.-based Music From The Sole, which draws on Afro-Brazilian influences. These artists transform a combination of tap and hambone to a glorious, millennial sensibility through the lens of hip hop and jazz.

“The art of flamenco includes a special kind of tapping — zapateado — as well as body-percussion elements that resonate with hambone.

” ‘Flamenco was being born in the mid-19th century. Certainly, by the 1902 arrival of the cakewalk in Spain, Black dance cultural motifs were transmitted, and flamenco artists expressly emulated Black American dance,’ says Dr. K. Meira Goldberg, author of Sonidos Negros: On the Blackness of Flamenco. “New forms that were created in explicit response to competition from Black artists in Spain emphasized percussive footwork, and over the past 30 or so years flamenco footwork techniques are increasingly influenced by tap and hip hop. It is fair to say that other modes of body percussion (hambone, or making percussion by snapping fingers, clapping hands or hitting hands on various parts of the body mixed with footwork) are also increasingly emphasized. Flamenco is always ready to absorb new performative ideas, and these ideas are reinterpreted and reinvented: In Spanish, the saying is “Llevarlo a tu terreno,” or “Make it your own.” ‘ …

“Indonesia has its share of corporeal clapping traditions as well. The Saman (‘dance of a thousand hands’) of the Gayo ethnic group of Aceh, Sumatra, is known across the island and performed by large groups to celebrate special occasions. Dancers sit on the ground with their legs crossed or folded beneath them, torsos upright. Though there are also mixed-gender performances today, ensembles had traditionally been separated by gender: Women do gentle tapping or patting on chest and thighs accompanied by hand-clapping, singing and rhythmically moving the torso and head, while the men move vigorously and their taps become slaps. …

“Exploring body percussion reinforces the understanding that everything we humans create has roots in something that went before. Even the most sublime innovations have a precedent. … The concealed riches of ‘the before time’ have become available on a global basis, thanks to social media, YouTube, streaming platforms and international touring by artists of every origin.

“Interestingly, hip-hop movements and music act as a unifying factor crossing cultural, class, racial and economic divides, transgressing differences, blurring boundaries and allowing a current generation of artists to travel beyond the assumed limitations of their genres, to try new things and experience other realms.”
