From the church comes the sound of a fragment of a motet, begun by the sopranos and swelling out afterwards in a six-part chorus. Tigrana sits on the table outside the inn and jeers at the piety of those peasants who, not being able to find room in the church, kneel outside and join in the devotion. To her dembal she sings a quaint and springy sort of tune which is thoroughly impudent in character. With a murmur of disapproval, which afterwards grows into a demand, the peasants indignantly ask her to desist from her frivolity. As she proceeds with her melody the peasants threaten to take stronger measures to stop the interruption to their prayers, and Edgar, coming out, rushes at once to Tigrana's defence. This open devotion to her cause apparently surprises the villagers greatly, and Edgar finds himself called upon at once to make up his somewhat vacillating mind. With rather curious and certainly sudden access of ardour, he rails against his lot, and curses the home of his fathers. Egged on to a species of frenzy, he rushes into the house and comes out bearing an ember from the hearth. In spite of the efforts of the villagers to restrain his mad impulse he flings the brand into the house, and clasping Tigrana to him, announces his intention of fleeing with her. Frank then rushes on to prevent their departure, and the two young men draw their daggers. A lull in the fray is caused by the entrance of Gualtiero and Fidelia from the church; and the old man's counsel for peace backed up by pious ejaculations from the crowd, seems likely at first to prevail. But Tigrana puts an end to Edgar's hesitation, and he attacks Frank with fury. Frank is badly wounded, and falls in his father's arms as the chorus curse Edgar for a reprobate, and the curtain falls as the house, now well ablaze, lights up the scene with its lurid glare.
