Girolamo Dalla Casa (also known as Hieronymo de Udene, died 1601) was an Italian composer, instrumentalist, and writer of the late Renaissance. He was a member of the Venetian School, and was perhaps more famous and influential as a performer than as a composer. Dalla Casa was a virtuoso player of the cornett, which he described as 'the most excellent of all the wind instruments ... because it mimics the human voice better than the other instruments do' (, 1:A2 verso).
