Assembly

1. Ensure all the tenons are greased with clarinet cork grease.

2. Grip the middle of the bottom joint with your left hand taking care not to bend the long side levers, and twist the bell onto the bottom tenon.

3. Grip the top joint with your left hand so that the side with no keys is lying in your palm and your fingers are holding the ring keys down; then grip the bottom joint in your right hand so that your palm rests on the bottom two keys holding them shut.

4. Now carefully twist the bottom joint onto the top joint tenon - if you are holding the joints correctly then the two metal extensions from each joint (the "bridge" keys) should not touch each other during this process; while still holding the two joints as described align the joints so that the rings are all in a straight line.

5. Insert the mouthpiece into the barrel with a twisting motion and fit the reed to the mouthpiece using the ligature -make sure the reed is on evenly so that the arc of the reed tip matches the mouthpiece tip.

6. Grip the middle of the top joint with your right hand taking care not to bend the long trill keys, and twist the barrel (with mouthpiece and reed attached) onto the top tenon until the reed is in line with the ring keys.

Taking care of the instrument

Grease the tenons before assembling the instrument if necessary.

After playing remove the mouthpiece from the barrel and remove the reed from the mouthpiece; place a mouthpiece mop in the mouthpiece to soak up any moisture; put the ligature back onto the mouthpiece and then fit the mouthpiece cap on; put the reed in its holder. (This routine will prolong the life of the reed and help prevent deposits forming in the mouthpiece).

Use a "pull-through" to clean out the barrel, top joint and bottom joint of the instrument after playing.

Leave the clarinet to "air" on a stand for 5-10 minutes after playing if possible to prolong the life of the pads. If the instrument has to be packed away often without being left to air then "pad savers" for the top and bottom joints will help - they will soak up the moisture left in the instrument.

Cleaning the instrument

Once a month leave the mouthpiece standing upside-down in mouthwash for 30 seconds and then wash out with soapy water but avoid wetting the cork too much (this will clear away any calcium deposits that have built up).

If dust or fluff does gather on the instrument then gently brush it away with a shaving brush.

Occasionally polish the keys to prolong the life of the plating. Use a silver cleaning cloth (for silver plated keys) or a brass cleaning cloth (for nickel plating).

If you feel competent enough then once a month use a precision screw driver to gently check none of the screws are working loose.

Cleaning pads

If the pads become sticky use pad cleaning papers to clean the pads: -dab on a little meths onto the paper with a cotton bud, place the paper under the key pad, hold the key lightly closed and pull the paper through. Now the pad is clean place a sheet of Yamaha powder paper under the pad, hold the key lightly closed, and pull the paper through.

Clarinet stands

Some players find the hassle of assembling and dis-assembling a clarinet can prevent them practicing. If the clarinet is placed on a stand after playing it can be left assembled and it will drain properly (although it is vulnerable to being knocked over).

Child players (with siblings) might be better taking the bell off the instrument and placing it under their bed with the holes pointing upwards, the instrument won’t drain effectively but it might be played more often and won’t get knocked over. In performances it is best for the player to keep hold of their clarinet, this way it won’t cool down (and play flat).

Clarinet cases and case covers

Clarinets are easily damaged and a well fitting instrument case is essential. The keys will be bent if the instrument can move in the case while being carried. Nothing else should be kept in the case unless there is a specific compartment for it (or it can fit in the bell).

Clarinet case covers are useful if you need to carry a stand or sheet music.

Clarinet mouthpieces, ligatures and mouthpiece caps

The mouthpiece is largely responsible for the response, tuning, and tone of the instrument so it is important to prevent deposits building up inside it.

The ligature should be regularly checked, the basic cheap metal ligature has a limited lifetime because the constant loosening and re-tightening of the ligature screws gradually distorts the metal so that it no longer holds the reed flat to the mouthpiece.

Mouthpiece caps are used to protect the mouthpiece - for some reason mouthpieces are regularly dropped! If the cap is plastic and is cracked, or it is metal and badly dented, replace it because it will not protect the mouthpiece if it is dropped.

Servicing and repair

The instrument should be serviced on average once a year to ensure it is operating correctly.

The pads, corks, and felts on the instrument (and also the adhesives which keeps these items in place) deteriorate over time. On older or poorer quality instruments the mechanism itself starts to wear and keys can become loose or jammed.

Usually such deterioration is gradual and the player subconsciously compensates by blowing harder and pressing harder on the keys. Without servicing the deterioration continues: the quality of tone diminishes; the instrument becomes less responsive; the tuning becomes unreliable. Eventually something major goes wrong and the instrument becomes unplayable and in need of considerable repair.

Players often blame themselves for the poor sound they produce when really it is the condition of the instrument that is causing problems. Test your clarinet with the following exercises, you should be able to play the notes without squeezing the keys too hard or blowing too hard:

  • Middle D down to middle using the left hand side lever

  • B/E to Bb/Eb using the “long” fingering (right hand finger 1)

The mouthpiece

The mouthpiece is the critical component of the instrument and is largely responsible for the tone, tuning, response, and dynamic range. Usually a clarinet is supplied with a suitable mouthpiece that matches the instrument but often this can be improved upon to some extent. There are many makes of mouthpiece designed to produce different quality sounds to suit different types of music and styles of playing - particularly Jazz. For classical players it is best to stick to the manufacturers own range of mouthpieces or try a Vandoran mouthpiece. 

When trying different mouthpieces it is important to make sure the bore of the mouthpiece matches the bore of your clarinet barrel. Also bear in mind that you may have to try different strength reeds if the tip opening or lay of the mouthpiece is different to your current mouthpiece. Refer to the page “information about clarinet and saxophone mouthpieces for advanced players”.

A good ligature

On a student mouthpiece the ligature is usually made of metal and has two screws. The ligature should fit onto the mouthpiece without twisting or bending, and the two screws should be parallel. With the reed off the m/p the "bands" (sides) of the ligature should nearly meet when the screws are tightened. With the reed on, the space between the bands should be less than 1.6 mm (1/16").

If the ligature does not fit properly or if the metal has become distorted then the reed will not sit on the mouthpiece correctly and the instrument will not play as easily and as well as it should. You should consider buying a new ligature.

If the mouthpiece manufacturer makes a matching ligature then buy that one, otherwise I would recommend the following:

  • For plastic mouthpieces - Rovner light or dark - around £15 to £20
  • For ebonite mouthpieces - Rovner as above, or BG ligature - around £20 to £30
