Baccusi's music is in the Venetian style, influenced by Adrian Willaert, Giaches de Wert, Cipriano de Rore and Andrea Gabrieli. He was a prolific composer, but to date no significant study has been undertaken of his music. His works, mostly published in Venice, include six books of masses, six books of motets and psalm settings, and seven books of madrigals, including a complete setting as a madrigal cycle of Petrarch's 11-stanza "Vergine". He also composed five- and six-voice settings of poems celebrating the Venetian victory over the Turks at Lepanto (1571). In the introductions to his 1596 and 1597 publications of masses and motets he mentioned the practice of instrumental doubling of vocal parts, something associated with the Venetian School; this is one of the first explicit references to a practice which had been going on for some time.
