If the animals are nominated for Grammy, these fox monkeys can win because they have a rhythm Indri Indri, a species of Madagascar fox monkey, is one of the few rhythmic animal species Biology: Indri is the largest living lemuriformes species, the only species to sing, and the best animal to study to see if there is a rhythm, co-author of the study Life Sciences And Chiara de Gregorio, a researcher in the Department of Systems Biology, said at the University of Turin, Italy. Rhythm was defined as “a persistent pattern of sound and silence.” Indri’s singing voice sounds like the howling pitch that penetrates the air is getting higher and higher. The researchers wanted to see if it was black. -White lemurs had a categorical rhythm of their ability to create different types of rhythm patterns. After 12 years of research into catching beats, scientists analyzed 636 vocal records from 39 adult Indris and found that they shared t. Two different rhythm patterns with humans. Like us, lemurs are primates. The first is isochronous, with evenly spaced pitches, says De Gregorio. The research team found that lemurs also sang in a 1: 2 ratio pattern. This is the case when the second interval is twice as long as the first interval. Both spacing patterns are in the intro of the song “We Will Rock”. Queen’s “you”, De Gregorio, explained. Further analysis revealed that male Indris held notes longer than females and sang longer durations between notes. According to De Gregorio, singing requires a great deal of energy, so longer intervals may allow male lemurs to sing longer. Collecting recordings of lemur singing voices has never been so easy. Being a canopy of Madagascar’s rainforest, researchers spent years chasing fox monkeys in the woods and listening to them singing. According to De Gregorio, furry mammals may not sing at all after a full day of tracking. Defense music is an important part of our lives, and the reasons are still being debated. “Our results are the origin of our rhythmic abilities, our love for dance, and our passion for music,” he said. The next step in her study is to determine if these endangered animals know how to sing at birth, or if it is a learned skill they practice.

If the animal is nominated for a Grammy Award, these lemurs have the potential to win.

That’s because they have a rhythm.

Indri Indri, a species of Lemuriformes in Madagascar, is one of the few rhythmic animal species. Studies show It was published in Current Biology on Monday.

Indri is the largest living fox monkey species and the only species to sing, so it is the best animal to find out if there is a rhythm, said research co-author Chiara de Gregorio (Life Sciences and Systems). Researchers in the biology department) said. University of Turin, Italy.

Rhythm was defined as “a persistent pattern of sound and silence,” she said.

NS Indri’s singing voice sounds like the howling pitch is getting lower and lower It penetrates the air.

Researchers wanted to see if the white-spotted lemur had the ability to create categorical rhythms, or different types of rhythm patterns.

Catch the beat

After 12 years of research, scientists analyzed 636 recordings of vocalizations from 39 adult Indris and found that they shared two different rhythmic patterns with humans. Like us, lemurs are primates.

The first is isochronous. This is the case when the notes are evenly spaced, De Gregorio said. The research team found that lemurs also sang in a 1: 2 ratio pattern. This is the case when the second interval is twice as long as the first interval.

Both interval patterns are in the intro to Queen’s “We Will Rock You,” De Gregorio explained.

Further analysis revealed that male Indris held notes longer than females and sang longer between notes. According to De Gregorio, singing requires a great deal of energy, so longer intervals may allow male lemurs to sing longer.

Collecting recordings of lemur songs has never been so easy.

Communication in the canopy

Tree-dwelling Indris live deep in the canopies of Madagascar’s rainforests, so researchers spent years chasing them in the woods and listening to them singing. According to De Gregorio, furry mammals may not sing at all after a full day of tracking.

Researchers don’t know exactly why Indri developed this unique talent, but she believes Degregorio may have evolved for long-range communications and territorial defense. Said.

Music is an important part of our lives, she said, and the reasons are still being debated.

“Our results can be important evidence for understanding the origin of our rhythmic abilities, our love for dance and our passion for music,” said Degregorio.

The next step in her study is to determine if these endangered animals know how to sing at birth, or if it is the acquired skill they practice.
