The flutes and harp, strong, irregular accents, and violent, percussive strokes in the timpani and xylophone can be heard, but a sweeping melody in the cellos cannot be identified. The correct answer is (c).
In this lively dance theme, reminiscent of Igor Stravinsky, the passage showcases strong, irregular accents, a rhythmic ostinato in the flutes and harp, and violent, percussive strokes in the timpani and xylophone. However, a sweeping melody in the cellos is not discernible. Aaron Copland, influenced by Stravinsky, employs these elements to create a dynamic and energetic atmosphere.
The absence of a sweeping cello melody contributes to the distinctive character of the passage, aligning with Copland's admiration for Stravinsky's rhythmic innovations and bold percussive elements. This blend of influences highlights Copland's versatility and his ability to incorporate diverse compositional techniques into his own distinct style, as heard in this lively and vibrant section.
