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 or, in the western half of the United States, scattering.
