 For example, many marches use more whole notes in the second strain than the first—as can be heard in "The Stars and Stripes Forever".Like the first, the second strain is usually repeated once, sometimes twice; but some marches, including "Emblem of Freedom", "Cyrus the Great" and the "Melody Shop", omit this repeat.In some marches, a short "introduction to the trio" is heard, often a repeat of the opening introduction, or it may be a different melody played by the whole band, a fanfare by the brasses—or a "percussion soli" (drum roll-off) as heard in "Semper Fidelis" by Sousa.
