Patriotic openers are approximately 15 to 20 minutes in length and serve to initiate the formal portion of a military, civic or governmental event. In this setting, the Band may perform a program of military and patriotic selections prior to the formal presentation of the Colors. The musical program must include the national anthem unless the ceremony includes a recital of the Pledge of Allegiance. During patriotic openers, the Band may not provide music for entertainment, such as dancing music, cocktail and dinner music or concert and show music.
