Maxakali territory once spanned at least three large valleys in the Atlantic Forest. Elders in the village remember how the forest supplied food, medicine and construction materials — in addition to serving as habitat for the yãmĩyxop, spiritual beings central to Maxakali beliefs.
“There were medicines in the forest for us,” explained Damásio. “When we had stomachaches, we would use the bark from the trees to feel better. But now, it’s just grass. The farmers burned everything.”
But the four remaining Maxakali reservations — reduced to 6,434 hectares (15,900 acres) of pasture — contain less than 17 percent of their original vegetation. Some experts consider the Atlantic Forest to be regionally extinct.
That absence has many Maxakali leaders turning to reforestation — and finding in their musical traditions an ecological blueprint of the past.
Singing organises life in Maxakali villages: Music, for instance, is used to cure illness, teach history or transmit practical instructions, like how to make bags or weave fishing nets.
“Songs tie together the whole Tikmũ’ũn social structure,” said de Tugny, the Hāmhi project coordinator, who is also a musicologist at the Federal University of Minas Gerais. “People don’t compose songs. They have songs.”
To have a song, she added, means being capable of taking care of the spirit considered to be the song’s creator.
Ancestral songs also provide an extremely detailed register of local ecology. Twelve musical canons, distinct in grammar and lexicon, total about 360 hours of song. Contained in the lyrics are hundreds of species of flora and fauna now extinct in the territory.
“We sing about everything: the saplings, the bananas, ourselves,” explained Manuel Kelé, leader of the village of Água Boa. “Even dogs have a song within our religion.”
One song, for example, lists 33 species of bees, some of which don’t have names in Brazil’s national language, Portuguese, and only two of which are currently present in the territory. The lyrics supply information about bee behaviour that many Maxakali have never witnessed first-hand.
“The songs are snapshots,” said de Tugny. “They are like photographs of every detail that exists in the Atlantic Forest: the names of insects, birds, plants, moments of relationship between an animal and a leaf. All these are registered.”
For the Maxakali, ritual songs also play a crucial role in helping the forest regenerate. Singing is a daily part of their work in Hāmhi’s tree nurseries.
Nursery caretakers not only sing to seeds as they are buried, but they also make music as part of the regular rhythms of harvesting and cultivation. Caretakers divide into groups, position themselves around the nursery, and sing in concert with each other. The song lyrics help participants remember the ecological knowledge of their ancestors.
And while some of the work at Hāmhi is dedicated to planting fruit trees and other crops, the project’s leaders see reforestation as key to reducing the region’s fire risks.
Since its inception in 2023, the Hāmhi project has planted over 60 hectares (148 acres) of fruit trees and 155 hectares (383 acres) of Atlantic Forest vegetation. The goal is a reforested area nearly twice that size.
Programme participants have also organised themselves into a provisional fire brigade and even created natural fire barriers, using traditional methods like planting species of fire-resistant vegetation.
“Songs help the forest grow,” said Damásio, the village leader. “We ask those who have died to help us. They walk here and assist us. We are calling on the forest to grow back.”
