Trombone / Bass Trombone support
Why the ERGObone?
Well, the reason for using it is actually very simple and obvious. The trombone weighs about 1,3 to 2,8 kilos (3,0 to 6,1 lb). Your left arm weighs about 4 to 5 kg (9 to 11 lb) and you keep both of them up at the same time. All the time when you play.
Of course, you can keep the trombone and the left arm up in a playing position, with continually tensed muscles. However, if you can avoid this, the important question is, is there really any sense in keep on doing it? Would the playing be better in the long run if your upper body could stay more relaxed?
