Tarquinia Molza (1 November 1542 – 8 August 1617) was an Italian singer, poet, conductor, composer, and natural philosopher.[1] She was considered a great virtuosa. She was involved with the famous Concerto delle donne, although whether she sang with them or coached them is not clear.[2] She also played the viola bastarda,[3] viola da mano, clavier, and lute. Trained in both distinctly male and female singing styles, her contributions helped combine them into the madrigal of the late Renaissance.[4]
