Next push the barrel onto the upper joint. I prefer not to twist this on as it avoids any
stress on the upper joint keywork. Place it on so the makers stamp is to the front.
Lay the clarinet down on the case or on a table while we
look at the mouthpiece. Never stand the clarinet on it's bell with no support, the instrument is unstable and easily knocked over causing damage.
Take the mouthpiece out of the case and pull off the cap and ligature, lay them down beside the case seperately. Be careful of the ligature, it is easily bent out of shape.
I am showing this next section with the mouthpiece off of the clarinet but normally I would do this after assembling the instrument.
Holding the thick end take the reed out of the water, put it in your mouth and gently suck off the water. Place the reed onto the flat table of the mouthpiece flat side down and hold it on with your left thumb. The tip of the reed should be level with the tip of the mouthpiece and even with the sides.
The bottom of the reed should be centred at the bottom of the flat table. Ensure the sides of the reed run evenly down the flat part of the flat table.
Take the ligature and place over the reed and mouthpiece with the screws to the top and right. Be careful not to catch the tip of the reed with the ligature. You will probably have to loosen off the screws to get the ligature far enough down the reed.
Tighten the top screw so the reed is held in place. Don't apply too much pressure or you will damage the reed and stop it vibrating properly, making it difficult to make a sound. Now tighten the lower screw with a little less pressure than the top one. Check the reed is firmly held by pushing gently on the side of the reed with the thumb. If the reed moves reposition and tighten the screws a little more. With practice you will know exactly how much to tighten the screws.
