José Juventino Policarpo Rosas Cadenas (25 January 1868 – 9 July 1894) was a Mexican composer, violinist, and band leader. Rosas was born into a poor Otomi family, in Santa Cruz de Galeana, Guanajuato, now renamed Santa Cruz de Juventino Rosas. In his youth he did whatever he could related to music, from ringing church bells to playing violin on the street, making music for his living from age 7 on. He used music for his ambitions to better himself, including composing a waltz in exchange for a pair of shoes.
