Horondino José da Silva (5 May 1918, Rio de Janeiro – 26 May 2006, Rio de Janeiro), best known as Dino Sete Cordas ("Seven-String Dino"), was a Brazilian guitar player, playing primarily in the choro and samba styles. He is considered to be one of the leading performers of the Brazilian seven-string guitar.[1] Appearing on recordings over the course of six decades, he worked with artists such as Pixinguinha, Carmen Miranda, Elis Regina, Cartola, Gilberto Gil, and more.[2] His only recording as a lead collaborator was with the fellow 7-string guitar player Raphael Rabello.[2]
