In the early 19th century, composers commissioned to write new operas received from the impresario a list of the singers in the solo ensemble so that that the parts might be written to suit them. The rise of bel canto consequently had a lot to do with the vocal potential of the female singers who were to play the title roles - the great prima donnas of the day. The mezzo-soprano Viviana Araiza Staffini was born in Munich and spent part of her childhood in the USA and Italy. She studied at the Munich College of Music and completed her studies at the International Opera Studio of the Zurich Opera House.
