Rhythmic similarities in the singing of gibbons and humans

Ricerca, somiglianze ritmiche nel canto di gibboni e esseri umani

Rome, Jan 11 (askanews) – A world analysis staff coordinated by the College of Turin has carried out a examine of vocalizations of white-handed gibbons, among the many most well-known of the duets singing, each in some Italian zoological parks and in Australia. His songs turned out to have rhythmic regularities partly much like human music. The examine “Isochrony and rhythmic interplay within the monkey duet” was revealed within the journal Proceedings of the Royal Society B.

The invention – explains Regno – is a part of a long-term challenge by the College of Turin and the Max Planck Institute for Psycholinguistics on musical traits shared by completely different species, a line of analysis aimed toward shedding gentle on biology and evolution. rhythm and music in our style.

The worldwide analysis staff, led by senior researchers Marco Gamba (College of Turin), Tommaso Savini (King Mongkut College) and Andrea Ravignani (Max Planck Institute), got down to search for musical talents in primates. Andrea Ravignani mentioned, “We have been attempting for a very long time to grasp what musicality traits are shared between completely different species, however research of the rhythmic elements of primate singing are actually of their infancy. On this examine, isochrony, which is how common a person rhythm is in a non-human animal, and two people rhythmically We explored the hyperlink between synchronization and the way coordinated it’s”.

A few of the analysis staff had beforehand studied the songs of one other singing primate, the lemur Indri indri of Madagascar, however the researchers needed to match these outcomes with an anthropomorphic primate species such because the gibbon. In addition they aimed to make clear the interplay results that happen throughout the duets of those gibbons.

“The presence of categorical rhythms corresponding to isochrony is a common musical function current in all human cultures, which we additionally observe right here in an anthropomorphic primate,” says Teresa Raimondi, PhD pupil in Organic Sciences and Utilized Biotechnology and first creator of the examine. like gibbons. We additionally present that a rise in vocalization frequency throughout singing is related to a rise in isochrony general, suggesting that physiological respiratory restrictions play a task in figuring out the rhythmic nature of singing.”

Giovanni Boris Di Panfilo recorded the songs of white-handed gibbons on the Huai Kha Khaeng Wildlife Sanctuary in Thailand, whereas Martina Zarantonello, Evolution of Animal and Human Habits graduate college students like Matteo Pasquali and Di Panfilo studied captive teams as an alternative. Relations at Falconara Zoo Park and Cappeller Wildlife Park close to Bassano del Grappa.

“The synchronicity additionally seems to be modulated in keeping with the emission context – These animals appear extra synchronous once they duet than once they sing,” says Marco Gamba, a professor within the Division of Life Sciences and Programs Biology on the College of Turin. alone. We additionally noticed statistical causality between one individual’s grades and one other individual’s grades. These research open new analysis views in a comparative perspective and take part within the development of a mosaic of musical talents in animal species”.
