Forr� means occasion, festival, dance, much more than just music. Since the 1940s the forr� has become known well outside of the borders of northeast Brazil. Accordion (concertina), the large frame drum called the zabumba, and the triangle are the typical instruments of the forr� band. Here they are played by musicians who mastered their instruments in childhood and are all closely associated with the forr�. The expression p� de serra (foothill) is used to describe everything from the that has come to the city from the provinces in raw and unpolished form. Forr� p� de serra differs from forr� urbano in not using any electroacoustic processing.
