Frevo is a wide range of musical styles originating from Recife, Pernambuco, Brazil, all of which are traditionally associated with Brazilian Carnival. The word frevo is said to come from frever, a misspeaking of the Portuguese word ferver (to boil). It is said that the sound of the frevo will make listeners and dancers to feel as they are boiling on the ground. The word frevo is normally used interchangeably either to mean the frevo music or the frevo dance.

The frevo music came first. By the end of century XIX, bands from the Brazilian Army regiments based in the city of Recife started a tradition of parading during the Carnival. Since the Carnival is originally linked to religion, they played religious procession marches and martial music, as well. A couple of regiments had famous bands which attracted lots of followers and it was just a matter of time to people start to compare one to another and cheer for their favorite bands. The two most famous bands were the Espanha (meaning Spain), whose conductor was of Spanish origin, and the 14, from the 14th regiment. The bands started to compete with each other and also started playing faster and faster, louder and louder.
