Compensating descant horns are rare. What sets compensating horns apart from standard doubles is weight. Because the air has to travel through the valves twice to play in the lower key (Bb), the valves need to be tight. With this horn the compression reading is 1.9, which is fabulous when you consider that the air has basically traveled through the equivalent of 10 valves. This horn is made of unlacquered red brass, has one small guard on the top of the horn where you pick it up. Perfect for that next B-minor mass gig. Red MB1 copy included. $3500
