"2. Duet." The abbot and doctor come strolling down the road in front of the house. They are deep in conversation on "professional" matters. To a series of outrageous pronouncements, the orchestra provides an accompaniment consisting of a set of variations on a pleasing Mozartian theme. Abbate Conspicuo, noticing they are in front of the lovely Annunziata's house, which is however all locked up, calls out several times to Matteo but receives no response. Finally Matteo cautiously opens the window partway to ascertain their identity.
