 The first section of a military march is called the "introduction" (I) or fanfare; it is typically 4, 8, or 16 bars long and played in marcato style, using forte (loud) dynamics and chromatic alterations to catch the attention of the listener.The introduction is usually the shortest section of a march and is almost never omitted.Still, examples of marches written without an intro include "Bugles and Drums" and "The Footlifter".
