Something unique is coming to the roof of George's Apartment Building-a symphony made out of wind put on by Mr. Zoobel and sponsored by Mr. Glass. The only propblem is that Mr. Zoobel does not know how to put on a wind symphony. Mr. Zoobel wants a loud "Bong!", a long "Whoo", a "Tink-tink-tink", and lastly a nice "Snap!", and George may be just the monkey to help. All he needs are ordinary household objects, and wind.
