Mas que nada is one of Brazil's most famous idioms, but its translation can be tricky. While it literally means "but what nothing," it's actually a playful exclamation used to say "No way!," "Come on!," or "Yeah, right!"
In this iconic song, the phrase is used to brush off any bad vibes. It perfectly captures a carefree, cool attitude, setting the stage for the singer who just wants to clear the way and enjoy the lively samba.
Sérgio Mendes and Brasil '66 kick off this bossa nova classic with pure attitude. The phrase "Mas que nada" is Brazilian slang roughly meaning "No way!" or "Yeah, right, get out of here!" It sets up an immediate boundary on the dance floor. The singer wastes zero time being polite, shouting "Sai da minha frente que eu quero passar" ("Get out of my way because I want to get through"). Why the rush? Simple: "Pois o samba está animado / O que eu quero é sambar" ("Because the samba is lively / What I want is to dance samba"). Nothing else matters here except clearing a path straight to the rhythm.
The song also roots its beat directly in Afro-Brazilian traditions. Mendes describes the track as a blend: "Este samba que é misto de maracatu" ("This samba that is mixed with maracatu"), calling out maracatu, a heavy, percussive folk rhythm from northeastern Brazil. He doubles down on its roots with "É samba de preto velho / Samba de preto tu" ("It is old black man's samba / Samba of black you"), nodding to ancestral rhythm and community spirit. It wraps up with a cheeky boast: "Um samba como este é tão legal / Você não vai querer / Que eu chegue no final" ("A samba like this is so cool / You will not want / Me to reach the end"). Once it starts moving, you really won't want it to stop.
Sergio Mendes (1941 to 2024) was a Brazilian pianist and bandleader, and one of the artists who carried bossa nova and samba to audiences around the world. Early in his career he played alongside Antonio Carlos Jobim, and in the mid 1960s he formed the group Brasil '66.
Their debut album gave them their first hit with this very song, a cover of Jorge Ben's "Mas Que Nada" sung in Portuguese with bright, breezy vocal harmonies. Decades later Mendes recorded it again with the Black Eyed Peas, introducing the tune to a whole new generation. He remains one of Brazil's most beloved musical ambassadors.
