Samuel Mergulhao Pontes, 16, a deaf student and member of the "Music of Silence Band", plays a bongo during their concert at the Municipal Theatre of Vinhedo city, 100 km (62 miles) from Sao Paulo, August 31, 2012. The technique of teaching music to deaf children was developed by Fabio Bonvenuto while working at the Madre Lucie Bray Municipal School for the Deaf in Sao Paulo in 2005, where the percussionists feel the music through vibrations rather than sound waves. The band recently received an invitation to play in the opening ceremony of the 2014 World Cup alongside the country's top musicians. Picture taken August 31, 2012.
