This partbook contains the "quinto" part for "Il Primo Libro de Madrigali a Cinqve Voci, con Tre Sesti, et Tre Dialoghi a Otto, Nouament e da lui Composti, & per Antonio Gardano dati in luce." Carli dedicated his First Book of Madrgials "all' Illustrissimo Signor Conte Alfonso Gonzaga Conte di Nuuolara." A table of contents at the end of the partbook lists the madrigals alphabetically in three categories: five-voice pieces, six voice pieces, and eight-voice dialoghi.
