What is a “Company Front?”
www.onlinedrumajor.com defines a company front as: A formation where the entire band or corps is in one large line, marching side by side.
In the video (above) from 1987 Garfield Cadets, the band comes together shoulder to shoulder in what is called a company front. Typically it’s in one or two long lines horizontally across the field (when looking at the band from the sidelines or from above).
Here is an image of the UCLA Bruin Marching Band Company Front in a endzone to endzone company front.
