Samba is a Brazilian musical style that was derived from African religious traditions. It is typically in 2/4 and uses a batucada rhythm.
The samba is now frequently used in popular music and is often correlated to the Brazilian Carnival.
An example of the samba in brass music is “Alpine Samba” by Derek Broadbent for brass band. Here it is played by Nationale Jugend Brass Band der Schweiz.
