Stomvi Flex Trumpet Mouthpieces

 

The Annulus, or “Gap” as it is commonly referred to, is the space (chamber) between the end of a trumpet mouthpiece and the beginning of the leadpipe. Stomvi Flex Mouthpieces are used with different couplers to adjust the Gap for each individual player. Purchase of a Stomvi Flex Mouthpiece includes 2 couplers (additional individual couplers are also available HERE)

 

These Stomvi Flex Mouthpieces are based on Bach Rim sizes.

From Stomvi:

Our C VR cup has more volume than a traditional "B" cup yet is considerably easier to play.

Our D VR cup has more volume than a traditional "C" cup yet is considerably easier to play.

Our F VR cup is similar in volume to a traditional "C" cup but has an acoustically advantageous shape.

Our G VR cup is similar in shape to our FVR cup but has less internal volume.

 

THE GAP IS THE MOST IMPORTANT DIMENSION THAT CAN EASILY BE ADJUSTED TO:

  • Make the upper register as easy as possible.
  • Improve your endurance.
  • Give you a full, resonant sound full of harmonics, or tonal colors.
  • Improve the low register.
  • Ensure the best intonation possible with your mouthpiece, your trumpet, and the way you play.
  • Give you more sound for less work.

 

WHAT IS THE "GAP", OR ANNULUS?

The gap is the space that can exist between the end of a trumpet mouthpiece and the start of the receiver.
 

WHY IS THE GAP IMPORTANT?

Adjusting the gap is the best way to ensure your set-up is in tune with Mother Nature’s harmonic series. When your set-up is in tune with the harmonic series, you get the maximum amount of sound along with ease of play.
 

WHAT DOES THE GAP DO?

The gap affects the location of the slots, or modes, and this affects the back pressure the player feels.
 

HOW DO I KNOW IF I HAVE THE RIGHT (OR WRONG) GAP?

If you experience:
    • Stuffiness in any or all registers
    • Too open in any or all registers
    • Bad pitch in any or all registers

Odds are high that adjusting the gap will improve things.

 

IS IT POSSIBLE TO CALCULATE THE GAP?

Unfortunately, no. This is because the gap is primarily an acoustic phenomena. Each player pushes their lips into the mouthpiece a different amount. This changes the effective resonance frequency of the mouthpiece and thus the relative intonation of the mouthpiece/trumpet system.
 

DOES THE GAP AFFECT THE AIRFLOW?

It does to a degree: When you have the correct gap acoustically for your mouthpiece, your horn, and the way you play, you are able to use your air in the most efficient manner. This is true whether you are someone who pushes a lot of air through the horn or for someone who does not.

When the gap is not correct acoustically, it will “feel” as though you have too much or too little back pressure, depending on a number of other factors.

 

WHAT IS BETTER; A SMALLER OR LARGER GAP?

Any gap can be correct. Empirical evidence shows that most players do better with more, versus less gap.
 

CAN I EXPECT TO USE THE SAME GAP WITH DIFFERENT TRUMPETS?

Generally no, it can’t be predicted. You must discover the correct gap for your mouthpiece and trumpet and the way you play.
 

CAN I EXPECT TO USE THE SAME GAP WITH DIFFERENT MOUTHPIECES?

Generally no, it can’t be predicted. You must discover the correct gap for your mouthpiece and trumpet and the way you play.
 

HOW CAN I ADJUST THE GAP?

The most effective and portable (meaning you can use it from horn to horn) method is to use our Flex Coupler system.
 

MY FRIEND AND I USE THE SAME MOUTHPIECE AND TRUMPET. SHOULD WE USE THE SAME GAP?

Most likely not, aseach player pushes their lips into the mouthpiece a different amount. This changes the effective resonance frequency of the mouthpiece and thus the relative intonation of the mouthpiece/trumpet system.
 
WHEN THE GAP IS ADJUSTED CORRECTLY, IT ALLOWS YOU TO USE YOUR AIR
IN THE MOST EFFICIENT MANNER POSSIBLE. WHEN YOUR GAP IS OPTIMIZED, YOU ARE GETTING THE MOST SOUND FOR THE LEAST AMOUNT OF EFFORT. THINK OF IT AS THOUGH MOTHER NATURE IS GIVING YOU “FREE GAS!”
