María Galli

María Felicia Antonia Galli Bagutti (13 June 1872 - 2 November 1960) was a Swiss-Uruguayan pianist, composer and music teacher. She was the first to approach the symphonic repertoire, the first to write an opera, a piano sonata and the first to venture into Latin American rhythms without forgetting the inclusion of tango (prohibitive for the females in her time).
