Barbara Strozzi (also called Barbara Valle; baptised 6 August 1619 – 11 November 1677) was an Italian Baroque singer and composer.
Strozzi was said to be “the most prolific composer – man or woman – of printed secular vocal music in Venice in the Middle of the century.” Her output is also unique in that it only contains secular vocal music, with the exception of one volume of sacred songs. She was renowned for her poetic ability as well as her compositional talent. Her lyrics were often poetic and well-articulated.
