This style has gained popularity recently, in particular among the student population of the southeast of the country (in the Forró Universitário genre, with important exponents today being Falamansa, and trios such as Trio Dona Zefa, Trio Virgulino and Trio Alvorada). Moreover, the accordion is the principal instrument in Junina music (music of the São João Festival), with Mario Zan having been a very important exponent of this music. It is an important instrument in Sertanejo (and Caipira) music, which originated in the midwest and southeast of Brazil, and subsequently has gained popularity throughout the country.
