Music professor Fabio Bonvenuto (L) plays the bongs with his deaf students and members of the "Music of Silence Band" (R- L) Weslen Santos de Souza, 14, Sivaldo Beserra Ferraz, 16, Jhenifer Olivia da Silva, 14, Kelvin Santos Magalhaes, 15, and Franciele Santos Oliviera, 14, at the end of 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 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.
