Only three more airs, and the first act of my opera is finished. With the aria buffa, the quartet, and the finale I can safely say I am perfectly satisfied--in fact, quite delighted. So that I should be sorry to have written so much good music in vain, which must be the case unless some indispensable alterations are made. Neither you, nor the Abbate Varesco, nor I, reflected that it would have a very bad effect--indeed, would ruin the opera--if neither of the two principal female characters were to appear on the stage until the last moment, but were to be always wandering about on the ramparts or terraces of the tower. One act of this might pass muster, but I am sure the audience would not stand a second. This objection first occurred to me in Linz, and I see no way out of it but to make some scenes of the second act take place in the fortress--_camera della fortezza_. The scene where Don Pippo gives orders to bring the goose in might be the room in which Celidora and Lavina are. Pantea comes in with the goose. Biondello pops out; they hear Don Pippo coming. In goes Biondello again. This would give an opening for a good quintet, which would be all the more comic because the goose sings too. I must confess to you, however, that my only reason for not objecting to the whole of the goose business is that two men of such penetration and judgment as yourself and Varesco see nothing against it. But there would still be time to think of something else. Biondello has only undertaken to make his way into the tower; whether he does it as a sham goose, or by any other trick, makes no difference at all. I cannot help thinking that many more comic and more natural scenes might be brought about if Biondello were to remain in human form. For instance, the news that Biondello had committed himself to the waves in despair, might arrive quite at the beginning of the second act, and he might then disguise himself as a Turk, or something of the kind, and bring Pantea in as a slave (Moorish, of course). Don Pippo is anxious to purchase a slave for his wife; and the slave-dealer and the Mooress are admitted into the fortress for inspection. This leads to much cajoling and mockery of her husband on the part of Pantea, which would improve the part, for the more comic the opera is the better. I hope you will explain my opinion fully to the Abbate Varesco, and I must beg him to set to work in earnest. I have worked hard enough in the short time. Indeed, I should have finished the first act, if I did not require some alterations made in some of the words; but I would rather you did not mention this to him at present.
