Ezra Jack Keats March 11, 1916 – May 6, 1983)
was an American writer and illustrator of children's books.
Keats is best known for introducing multiculturalism into mainstream
American children's literature. He was one of the first children's book
authors to use an urban setting for his stories and he developed the
use of collage as a medium for illustration.

An excellent and relatively non-preachy story with lovely art. ( )

Keats depicts tenement life through the eyes of two young boys as they search for the origin of harmonica music they overhear.

The book can be used to note about making inferences. It has great illistration to show children how the setting can show the mood of the story ( )

This story is about children in an apartment building that hear harmonica music. They search their building and listen to every apartment, but they can't find the music. This book can be used to teach problem by asking "is the character unsure of something?" The answer is yes because the characters are unsure of where the music is coming from.
