You first place the attaching ring with an Eye Bolt to the clarinet between the upper joint and middle joint, above the thumb rest. It is similar with the RMD Riedl Marching Lyre ring.
You need 10 to 15 seconds to do this.
In the support rod there is a coiled spring in order to give a smooth and soft floating feel to the clarinet. Your hands and arms are no more supporting the weight of the instrument.
Now the weight of the clarinet is transmitted to the to the chair. You can use also the longer monopod extension (sold separately) and transmit the weight to the floor. With the extension you can play either sitting or standing.
Today we do understand the ergonomic challenges involved in playing. You need some time to readjust your perception about clarinet playing. You need a moment to get used to the different feeling of the nearly weightless instrument. After the readjusting period, you will enjoy playing with less tension.
