The syncopated riff in The Charleston forms the basis for how many bars?

• A. Fifteen of the thirty-two bars
• B. All thirty-two bars
• C. Eight bars
• D. Twenty bars

Answer: (A)

The main idea here is how a single rhythmic idea can act as a unifying thread through a tune’s form. The syncopated riff in The Charleston is the driving motive that shows up repeatedly and shapes the character of the melody, tying much of the piece together. Across the 32-bar form, that riff is heard in many measures, giving the tune its recognizable groove and shape. However, there are sections—such as a contrasting middle or bridge—where the melody shifts away from that riff to provide variety. When you account for every bar in the 32-bar layout, the riff-based material covers fifteen bars in total, with the remaining bars featuring new or contrasting material. So the correct choice reflects how the riff serves as the backbone for most of the piece, but not every bar.
