Ubirajara (Bira) Guimarães Almeida (born 1943), better known as Mestre Acordeon, is a native of Salvador, Bahia, Brazil, and a master (pt.: mestre) of the Brazilian folk art Capoeira. His international reputation as a teacher, performer, musician, organizer, and author is built upon fifty years of active practice, as well as research into the origins, traditions, political connotations, and contemporary trends of Capoeira. Mestre Acordeon has traveled extensively to promote Capoeira outside Brazil.
Acordeon was a student of the legendary Mestre Bimba in the late 1950s, and began teaching Capoeira himself in the early 1960s. In 1966, he founded the Grupo Folclorico da Bahia that performed the show Vem Camará: Histórias de Capoeira in the Teatro Jovem in Rio de Janeiro. The show presented an approach to Capoeira that influenced a new generation of young capoeiristas and affirmed the concept of grupo de Capoeira and today’s capoeira regional. He won three Brazilian Capoeira National Championships in the 1970s.
At the end of 1978 Mestre Acordeon came to the United States and soon introduced Capoeira to the West Coast. 1979 became a turning point in the global growth trajectory of Capoeira. Since then, and for the past four decades Mestre Acordeon has been the guiding light to a generation of Capoeira practitioners who followed him north to make a good living abroad through their art.
Mestre Acordeon maintains the United Capoeira Association (UCA) with several associated schools. He also has created the Capoeira Arts Foundation in Berkeley, California which sponsors UCA and Projeto Kirimurê, a social program for children in the neighborhood of Itapoã in Salvador, Bahia, Brazil.
