We do not have any of his nine Masses on records, for this disc presents five Mass movements selected from five different Masses, all for four voices. Three of them had been published in a single volume by Petrucci, an indication of his stature as a composer during his lifetime. The Sanctus of the Missa Re-fa-mi-re-fa has a remarkable chromatic Hosanna. The program also includes a Salve Regina, several pieces in the Chant sur le livre style (one or two polyphonic voices are added to a chant melody), and several chansons that have proved to be popular on records already.
