A scramble band - also known as a scatter band - is a particular type of field-performing marching band with distinct characteristics that set it apart from other common forms of marching bands; most notably, scramble bands do not normally march. In fact, the name comes from the way in which the band moves between formations – members run to each form without using a predescribed path; this is known as scrambling.

A marching band is a group of instrumental musicians who perform while marching, often for entertainment or competition. They are most popular in the United States, though not uncommon in other parts of the world. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military style, that includes an associated organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags, rifles, and sabers.
