Prop Euphonium – Brass: A non-working replica, the Prop Euphonium in Brass is intended for stage use in a variety of productions. With its unique shape and valves, it has a polished brass finish that closely resembles a real euphonium, but it lacks the internal parts needed for actual play. This prop is perfect for stage sets, movies, photos, or any occasion where a euphonium’s visual presence is desired without the instrument having to make sound.
