 Overtones in the chalumeau
Author: ChiTownClarinet

Hello,

In the last year, I replaced my old Buffet R13 with a brand new Buffet Festival clarinet. overall I love the instrument, and I tried out about 10 clarinets before deciding on this particular one.

One glitch I've noticed, however, is that I occasionally get overtones (i.e. harsh squeaks) in the chalumeau register. This most often happens when playing forte or above, with hard attacks, or when rapidly jumping from clarion register down to the chalumeau while tonguing attacks (especially noted playing Mozart's Clarinet Quintet 4th movement).

I never seemed to have this problem in the past. I took a long hiatus from playing (about 10 years) and have recently been playing avidly again. I have been paying a lot of attention to my embouchure but cannot figure out what I'm doing wrong.

I've taken the instrument (which was hand selected by a professional) to 2 different technicians, both with great reputations, who cannot find leaks or other problems. So I'm left to think this is something I'm doing with my mouth. I used to be quite proficient at jumping between registers and I imagine I just lost something during my hiatus.

I'm currently not working with a teacher, just playing casually, so any advice would be greatly appreciated!

ChiTown -

Don't begin a note with an *attack*. Keep the air pressure up and lay the tip of your tongue at the tip of the reed and just back of it to stop the vibration. Move your fingers and then gently remove your tongue to *release* the tone. Your embouchure and air never stop.

Also, the finale of the Mozart Quintet is a theme and variations, so the theme must always be there. The first variation is not a big clarinet solo. You don't even have the melody, which is in the second violin and viola. They (and later the viola and cello) have the solo. Your part is like the thinnest possible spider web, laying over the melody and glistening with dew.

It's the same in variation 4, and nobody has the melody in variations 2, 3 and the first part of variation 5 (adagio). You have a heavily decorated version in the second half of variation 5, but you must organize it around the melodic notes in your head. The strings also play the melody in the coda, while you soar over with a descant, like a feather in the breeze.

That's why you should always practice from the score <imslp.org/wiki/Clarinet_Quintet_in_A_major,_K.581_(Mozart,_Wolfgang_Amadeus)>. You need to know everything that's happening, not just your part.

As to voicing, there is a slight change in your mouth when you move from one register to another. The back of your tongue should stay high and the front part low. The middle part raises slightly and maybe moves slightly forward as you go up, and lowers and moves back as you come down.

Practice this by playing low E, hearing third-line B loud in your head and pressing the register key so slowly that you don't know when the tone will jump up to the B. Then move chromatically up, F to C, F#/C# and so on to first-space F/C. By the time you reach the last pair, you'll notice that your tongue position changes automatically for the high note. Hearing it first is the key.

The next step is to play A below the staff, gradually press the register key for E and then gradually roll your left index finger down for C#. Carry the warmth of the A up to the E, and carry the warmth of the A and the clarity of the E up to the C#. And then go chromatically up until you reach (side-key) Eb/Bb/G. The G will be flat, but don't worry. This is just an exercise. Again, hear before you move, and notice the subtle voicing changes as you change registers.

You really need at least a few face-to-face lessons to get you back into the saddle. What I've described is only what I do, and your way will always be at least a little different.

Keep warm in ChiTown. When I was 10, I walked down the long spit from the Planetarium to the Aquarium on a really bitter day with winds screaming in off the lake, and 60 years later I still remember being ready to die. [grin]

Ken,

Thanks for your very wonderful advice! I used to do the register transition exercise in my younger years and sort of forgot about it. I'm going to start adding that to my warm up exercises. And I appreciate your embouchure/mouth shape advice!

Your story about being cold in Chicago is very pertinent right now. We're in the middle of a relentless arctic bashing! But it's beautiful here in the summer!

Take care!
