The mouthpiece is the most individual part of the clarinet. The mouthpiece, along with the reed, is what creates the sound and tone of the instrument. Because of many innovations with the clarinet mouthpiece, players have many options for their sound. Today, there are two main materials that the mouthpiece is made from: plastic or hard rubber. The plastic mouthpiece is a cheaper, cost effective version that comes with all basic clarinets, however, it will not sound as good as the hard rubber. The hard rubber mouthpiece is more expensive, but produces a much more complex sound. Crystal mouthpieces are another option.
Along with the mouthpiece, there is the reed. The reed is a piece of cane that has been shaped in order to vibrate a specific way, depending on the hardness of the reed. The hardness of the reed can change the sound dramatically. Soft reeds allows the player to play softer easier, but it is often harder to tune. Hard reeds allow players to produce a louder and fuller sound, but requires a stronger embouchure (mouth muscles) to create a good sound.
The reed is affixed to the mouthpiece using a ligature. This device can be made from metal, leather, plastic, and even a string. The ligature is used to help keep the reed on the mouthpiece firm enough so that is stays, but not so tight so that the reed does not vibrate. If the reed does not vibrate, then there will not be any sound produced.
- Put cork grease on the tenon
- Place the reed in your mouth to soak it. Place the flat side, or the facing, on your tongue. Make sure that you place the tip of the reed in, not the butt. Continue to set up your mouthpiece.
- Hold the mouthpiece in your left hand and the barrel in your right. The narrow end of the barrel is where the mouthpiece attaches to.
- Line up the barrel with the mouthpiece and slowly push and twist the two parts together until they in place.
- Loosen the ligature screw. Do not remove them. Slide the wide end over the mouthpiece. Make sure that the screws are facing the right side of the mouthpiece.
- Hold the mouthpiece/barrel in your left hand. With your left thumb, push up on the ligature to create some space. Remove the reed from your mouth and slide the butt of the reed under the ligature. Make sure that the flat side of the reed is against the flat side of the mouthpiece.
- Line up the tip of the reed with the tip of the mouthpiece. Make sure that the reed is straight.
- While still holding the reed with your thumb, lower the ligature over the table of the reed (the thick part of the reed).
- Tighten the ligature screws just enough to hold the reed snug in place.
