I am a teacher and this is one of my favorite books to read to my kids. The story is about Sam, a kid in an apartment building in a city on a rainy day. He observes all the sounds he hears but he is enchanted with the sound of music coming from one of the apartments. He and his brother set off to find the source of the sound. When he finally finds it, the vivid imagery is magical. When the man plays the music, Sam says, "He played purples and grays and rain and smoke and the sounds of night." Gorgeous.
