The Adams 5-Valve Non-compensating euphonium

A quick demonstration of the Adams 5-Valve non-compensating euphonium. This is a fully-realized prototype instrument that is intended to compliment, not replace, current compensating euphoniums. The open low register and multiple valve combinations enabled by the inclusion of the Gb fifth valve are just some of the special characteristics of this instrument. Even if a musician doesn’t venture below the staff that often (but still wants a fully chromatic instrument) the shorter piston valves (when compared with a compensating valve extinguisher) can be appreciated with every swift passage.
