y’all i bet they’re talking about the balance, when the trumpet comes in on this video, it’s definitely treble heavy. don’t hear too much of that sweet trombone on this one.
My guy, brass bell-front valve instruments in any key have been allowed since 1999, and in 2014, the DCI Board of Directors passed a rule change that changed their definition of a "bugle" to allow the entire brass family, meaning everything from a piccolo trumpet to a sousaphone. RIP your old ideas of "G Bugle Master-Race"
So far, trombones have only been used for sections of a show that musically require one for the slide. Nobody uses them throughout an entire show. Its usually the baritones or euphonium players that switch to trombone mid show for the trombone parts. Trombones are just too large of an instrument to use in intricate drill throughout an entire show
