He is assisted by his older sister Annalisa who teases him about his ability to sing. Indignant, Karl challenges her to a singing contest in which they both try to out-sing each other. Mama brings Karl's new coat and lunch box and then breaks down and weeps at the thought of his going. Papa comforts her and then suggests that they all sing together once more before Karl goes. Karl says he could never forget it because it is his favorite song.
Snow falls slowly.
After a loving farewell, Papa escorts Karl through the forest to meet the stage coach for Salzburg. Wilhelm has never heard it but keeps it to teach it to his boys. When he finally gets it and opens it, there is a Christmas pudding inside, complete with a large sprig of prickly holly. They hear the choirmaster and Schmallplatz returning and Rudi hides the pudding behind his back, as he sirs in the last row and Karl must sit right up in front. They sing for Schmallplatz and then he requests a solo.
