You need to attach a stainless steel plate permanently to your horn with flexible plastic ties. The plate is cushioned with soft paddings to protect your instrument surface. The plate has several holes so that you can find the right one for best balance. Stick the support head through the hole and secure it with the cotter pin so that it does not fall when yo lift the horn.
The support part has a stainless steel rod and the support head on top of it. You can move it up and down in the black tube. Simply open the screw, adjust the instrument in the desired height and lock up the screw. Nice and quick. The horn is now floating at the desired height on a smooth spring.
Even if the height screw is locked you can easily turn your instrument in any direction at any time. This enables you to play the horn without any tension in arms, shoulder, back or throat - quite a relaxing feeling!
When you play sitting down, place the lower end of the tube to the chair. Now the horn floats weightless but as the connection is loose, you can turn the instrument very freely while playing. When resting place the horn to your lap like usual. The support rod and the tube hangs from the plate between your legs.
Playing standing up
When you play standing up, put the support tube in a special belt pocket. Now the weight of you hands and the instrument is transmitted through the belt to your legs! You can walk and move freely, even march with the ERGObrass euphonium support while you play!
Optional telescopic extension:
There is available also a telescopic support extension for playing both standing up and sitting down. It enables player even more freedom while playing because a longer support allows larger movements at the same time as it transmits all the weight to the floor. The extension has five sections and four quick locks to get the extension in right height.
The extension set does not belong to the normal full set but can be purchased as an additional set.
Freeing up the upper body can also help the most important aspects of brass playing: breathing and air flow. With ERGObrass support, the only task remaining for the hands is to balance the horn and keep the mouthpiece in the right place and angle for each situation, and then your fingers stay relaxed on the valve triggers. With the weight of the horn taken off the body, the player's touch and feel for playing are improved and stresses are reduced.
