765. The reason I know all the things you have been doing to me is because they are the exact same things I did to my music teacher when I was young, and the same as my father did to his teacher. You girls think you have made all of this naughty behavior up yourselves, but the truth is all of these things have been going on for years and years. And if you have the misfortune to have to teach music when you are older it will happen to you also.
766. The persecution of the music teacher is a grand tradition that goes back thousands of years, and you may wonder why it is that the bad children engaged in these pranks are not caught and punished. The answer is very simple. The music teacher looks on with a blind eye because he is kind, because an unkind person can not master the discipline of music, and secondly, because when one sees children playing the same pranks we played as children it gives one great pleasure.
767. But now back to my story of Vivaldi. Since it was a choir he had to compose and conduct for, it was when the girls were singing that they gave him the most trouble. I say,'singing', but the word really should be mumbling. No matter how he encouraged the girls, they were too shy and awkward to try to really sing.
768. If Vivaldi resorted to having them sing the common tunes of the street which they were familiar with he had better luck, and those tunes, since the girls sang in unison, went very well. But as soon as he tried to get them to sing more complicated works, works involving part singing, they resorted to near silence. Just like myself, he resorted to threats and reproaches and it sometimes happened that all the girls would manage to sing some work of his with adequate feeling.
