Carlo Gesualdo da Venosa (c. 30 March 1566 – 8 September 1613) was Prince of Venosa and Count of Conza. As a composer he is 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.
