Anyone with an interest in cavaquinho should know about this project, spearheaded by Pedro Cantalice, who was CCNE's cavaquinho instructor in 2023. Although all the talking on the site so far is in Portuguese, there are many pseudo videos (just audio, usually) featuring choros performed on cavaquinho, many of them by extremely talented cavaquinistas who would no doubt be forgotten were it not for projects of this sort.

Here's a (DeepL) translation of the blurb about the project:

Memória do Cavaquinho Brasileiro is a digital collection dedicated to researching and disseminating the different trajectories of the cavaquinho in Brazil. Through the publication of audios, videos, texts and images on social networks, it covers general subjects that are directly linked to the instrument, such as its performers, composers, teaching methods, academic works, scores, curiosities and so on.

With the mission of expanding knowledge about the small chordophone, the collection dialogues with different methodologies for collecting data, from oral history to documentary research.

Its main achievements include the lecture “Memória do cavaquinho brasileiro no Arquivo Nacional: pesquisa em música no acervo”, held at the Arquivo Nacional do Brasil - RJ, in February 2019, and the article of the same title published in the magazine Acesso Livre n.11 jan.-jun. 2019.
