The Full Form of MPB is Musica Popular Brasileira.

Música popular brasileira (Portuguese pronunciation: [ˈmuzikɐ popuˈlaʁ bɾaziˈlejɾɐ], Popular Brazilian Music) or MPB is a trend in post-bossa nova urban popular music in Brazil that revisits typical Brazilian styles such as samba, samba-canção and baião and other Brazilian regional music, combining them with foreign influences, such as jazz and rock.

This movement has produced and is represented by many renowned Brazilian artists, such as Jorge Ben Jor, Ivan Lins, Belchior and Dominguinhos, whose individual styles generated their own trends within the genre. The term is often also used to describe any kind of music with Brazilian origins and “voice and guitar style” that arose in the late 1960s.

Variations within MPB were the short-lived but influential artistic movement known as tropicália, and the music of samba rock.
