A modern "pagode" style tune performed by Caraivana, one of Brazil's great new roots bands. The tune is samba-based, but very much in the roots mode.

Chords and Brazilian rhythms in the high strings of the cavaquinho, 7-string guitar slithering connecting basslines countermelody style, surdo (actually tom-tom in this case) on the backbeats. It's a 2/4 style, but 4/4 cut-time can be worked to the same effect.

"Ser feliz" which means "be happy"

Great infectious groove, and I can't help but think that this could be done in BIAB.
