This tune was included in CCNE's 2022 Core Repertoire and is now in our Supplementary Repertoire packet, which you can find on this page.
Here's the accompaniment video that our teachers prepared for us that year:
Raul de Barros' album "Brasil, Trombone" opened with his most popular composition, now a standard at rodas de choro, "Na Gloria". Track 2 was the best-known tune of another trombonist, Astor Silva, "Chorinho de gafieira".
In the words of Samuca Muniz, who prepared this sparse and (IMHO) excellent accompaniment:
"The idea behind these playbacks is to give the musician total freedom to explore their creativity. That's why the 6-string guitar was recorded in a more succinct way, without the obligatory basses commonly found in choro and the like."
I use it to practice accompaniment of cavaquinho, as well as soloing. Very helpful.
This video featuring Paulo Moura, Zé da Velha and Silvério Pontes is from the Mika Kaurismäki film, Brasileirinho
