Feia (Ugly): Explanation by Jacob do Bandolim here: https://www.youtube.com/watch?v=KYkyTkrhv6o
Remelexo (Swing): This choro - a jazz-like style choro in Izaías do Bandolim’s opinion - was composed, in Jacob’s own words, as an answer to some reviewers of the time who considered him a “square” musician (a derogatory musical slang meaning the traditional musician with no swing talent). According to Deo Rian, Jacob used to say that “Remelexo” was somewhat a teasing, because he used to play old songs and people said he played ‘conventionally’.” Then he composed Remelexo and asked Fernando, a guitar player who used to play with him at the time, to improvise as one may hear in the original recording. But he used to say that it wasn’t really a choro. It was more like an answer to reviewers.
De Coração a Coração (From one Heart to Another): According to both Deo Rian and Izaías do Bandolim, this waltz would have been composed in 1967, in Brasília, to honor his cardiologist, Dr. Luciano Vieira.
Doce de Coco (Coconut Sweet): According to Deo Rian, Jacob composed this choro because he was very fond of coconut sweet and ice-cream.
Vascaíno: Deo Rian also says that this choro (Vascaíno, meaning a supporter of the Vasco da Gama Soccer Club) was dedicated to his son, Sérgio Bittencourt, who was a fan of the Rio de Janeiro famous soccer team.
Bole-Bole (Shaking the Hips): Deo Rian says that Jacob got his inspiration to compose this choro in a popular dancing place then located at Rua Real Grandeza, in the district of Botafogo, Rio de Janeiro, next to the guitar player César Faria’s place.
Treme-treme (Shaky): Deo Rian says that Jacob was inspired by the Brazilian Manjar Branco, a kind of a sweet dessert with a pudding-like shaking consistency to compose this choro.
Vibrações (Vibrations):Deo Rian also says that in March 1964 Jacob left his car at a gas station to be washed and went to Mr. João Dormund’s place (a common friend of theirs), in the district of Jacarepaguá (Rio de Janeiro). That was a kind of a retreat of the old guys, a place where Léo Viana - Pixinguinha’s brother, Jacob himself, Deo Rian and many other old musicians used to get together. There, he asked for a pencil and some music sheet paper and wrote the song without any instrument, asking João to give it to the guys to play the following Sunday (most of “the guys” were in their 70s). On Monday João went to Jacob’s place and asked: “Do you have any idea of the masterpiece you just wrote?” Jacob said: “You might as well choose its name, because I’m dedicating it to you.” João was a devout spiritualist and gave the song the name "Vibrações" (Vibrations).
