Pari's only surviving music are three books of madrigals, all published in Palermo between 1611 and 1619. Three other books of madrigals written prior to 1611 are lost. The collection published in 1611 includes a setting of Guarini's famous "Il pastor fido", and the 1619 collection is subtitled "Lamento d'Arianna"; it is clearly influenced by the famous composition by Monteverdi. In the "Lamento d'Arianna" collection, Pari derived most of the motivic material directly from Monteverdi, but worked it into a dense, archaic contrapuntal texture more akin to Gombert, who had died sixty years earlier, than to the currently popular style of monody.
