Winter guard
Winter guard (sometimes spelled "winterguard") is an indoor color guard sport and performance art derived from military ceremonies. Modern winter guard is a competitive, performance-based activity which incorporates choreographed staging, dance, and manipulation of equipment such as flags and prop rifles and sabres (also known as "spinning"). Unlike traditional color guard, winter guard performances and contests are held indoors, usually in a gymnasium or an indoor arena. Performances typically last three to seven minutes and are generally accompanied by recorded soundtracks rather than live music. However, the use of live instrumentation (acoustic and electronic) and vocalization have grown in popularity. Winter guard is most present in the United States; independent units have also been formed in Canada, the Netherlands, the United Kingdom, and Japan. Winter guard ensembles often perform at judged competitions officiated by local and regional associations using criteria developed by Winter Guard International, host of the annual Winter Guard International World Championships in Dayton, Ohio. The World Championships event purportedly attracts in 60,000 visitors to the event annually. Scoring attempts to rank units on the repertoire and achievement of aspects of each performance such as unity, quality, range, precision, skill, design, and effect.
