What are some of the sounds of the monastery. Why are these sounds important to Robin?

Music accompanies Robin wherever he goes, whether he is singing in the choir of St. Marks' monastery or listening to the songs of John-go-in-the-Wynd. The learning of carols and the building of his own harp are important activities that help Robin recover and feel like he can participate in life once again. It is the "mournful and slow" tune of John, played on his harp, that alerts the shoemaker to help them cross the wall back into the castle. And in the final scene of the story, Robin asks to sing a Christmas carol in front of the King and Queen, right after he has been awarded the crown of jewels.
