Henry, a tuba player, finds playing solo much too lonely. As luck would have it, he meets Elsie, a piccolo player. Henry falls for Elsie's toodle-dee "way-up-high" notes. And Elsie loves Henry's mellow, "way-down-low" notes. However, soon after their marriage, Henry decides that what he'd really like to have is a family band. Thus begins Henry and Elsie's musical journey as they add kids and instruments to their growing ensemble. After a measure of discord and dissonance, the family band comes together in harmony to play their surprising and spectacular finale. The music sparkled, thundered, lit up the sky, On that marvelous, musical Fourth of July.
