The kazoo is rare in European classical music. It does appear in David Bedford's "With 100 Kazoos", where, rather than having professionals play the instrument, kazoos are handed out to the audience, who accompany a professional instrumental ensemble. Leonard Bernstein included a segment for kazoo ensemble in the First Introit (Rondo) of his "Mass." The kazoo was used in the 1990 Koch International and 2007 Naxos Records recordings of American classical composer Charles Ives' "Yale-Princeton Football Game", where the kazoo chorus represents the football crowd's cheering. The brief passages have the kazoo chorus sliding up and down the scale as the "cheering" rises and falls.
