Although of Spanish descent, Marianna Martines spent her entire life among the aristocracy in Vienna. In 1773 she was accepted into the prestigious Accademia Filarmonica of Bologna, and she later founded a singing school. She is reported to have composed over 200 works, of which sixty-nine are known to have survived and represent the largest extant collection of music by a woman in the classical period.
