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. Another example of a trio introduction is found in "Twin Eagle Strut" by Zane Van Auken.
