As Elmo and Zoe take a walk in the city, they take note of the rhythm and beat of all the sounds they encounter. From the honking of a horn to the movement of traffic, from the the clang of machines to the wails of sirens, the city’s noise is like music. Adults read the toe-tapping rhythm of the text and children chime in at predictable intervals with a repeated chorus. Richly detailed illustrations add another dimension to the simple text.
