Gesualdo da Venosa

Carlo Gesualdo da Venosa (between 8 March 1566 and 30 March 1566 – 8 September 1613) was an Italian nobleman and composer. Though both the Prince of Venosa and Count of Conza, he is better known for writing madrigals and pieces of sacred music that use a chromatic language not heard again until the late 19th century. He is also known for killing his first wife and her aristocratic lover upon finding them in flagrante delicto.
