The ERGObrass support is specially designed to be a handy medium to enable the player to keep his or her hands and upper body completely relaxed by removing the need for the body to support the weight of the instrument. Instead, the ERGObrass support will transmit the weight of the trumpet to the chair or through the belt to the legs. Freeing up the upper body can also help the most important aspects of brass playing: breathing and air flow. With the ERGObrass, the only task remaining for the left hand is to balance the trumpetand keep the mouthpiece in the right place and angle for each situation. Then, of course, your fingers can act relaxed on valve triggers. Special fixture for cornet available seperately - please contact us for details. Also additional fixtures for trumpets in other keys.
