Surveys scholarly views of jazz's rhythmic and metrical structures in the 1920s (at the outset of Copland's career) focusing especially on Copland's own writings on the subject. Analyses of selected passages from Copland's piano concerto, the second piece of Four piano blues, the Piano variations, the piano sonata, the clarinet concerto, and Appalachian spring help to assess the ambiguity surrounding the identification of jazz-based rhythmic influences in Copland's music.
