793. The first two movements went off without any difficulty, but in the third section, the section involving the quartet of the mothers, Simona and Netochka began to sing slightly out of tune. Simmona sang slightly sharp, and Netochka sang a little flat. They did this very skilfully so that at first it seemed accidental, but in the slower sections it became more pronounced.
794. It is very easy to describe what Simmona and Netochka sounded like in the quartet. Have you ever been awakened in the middle of the night by cats confronting each other and preparing for a fight. If you have heard that sound then you know exactly what the girls sounded like. And just like with cats out in the yard at night, it just wouldn't stop, but went on an on getting louder and louder.
795. Poor Vivaldi. He knew he was being made a fool of by the girls, but what could he do? He was used to sitting back and letting the girls direct themselves because they had been doing the piece with such inspiration, so when the caterwauling began he was not even paying attention to what was going on.
796. But things were even worse that that. The orphanage fathers believed that it was all intentional, and that what they had heard is what Vivaldi had intended for them to hear, and they were livid.
