When learning to play Brazilian jazz it is best to go to the primary sources, the original and other seminal recordings recorded in Brazil, both past and present. At the end of this sample of Brazilian recordings is a fine recording by Kenny Barron, who it must be said, has listened to the original recordings.
Spend an afternoon playing the melody with the recordings, mimicking as much as possible what you hear. Then add the chords.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
