Tuba Mouthpiece Overview and Fitting Guide

Converting to a Wedge? Here's an Overview of our Tuba Mouthpiece Sizing

Rim diameters range from 1.26 inches (32 mm) to 1.32 inches (33.5 mm) measured at .05 inches into the cup in the long, vertical axis of the oval. They are named by the size in inches, so that a 1.28 inch rim is called a 28 rim, a 1.32 inch rim is called a 32 rim, etc.
Cups range from a shallow F cup for F tuba, through G, H, and D cups.

Looking for a quick way to find a Wedge similar to your current mouthpiece?
If you are happy with your current mouthpiece and just want to know what the Wedge design can do for your playing you can simply select a mouthpiece using one of our Tuba Mouthpiece Comparison page.

Are you thinking that you need a different size?
The best way to get fitted is to complete a fitting survey, or book a phone call or Zoom chat with Dr. Dave by visiting our Contact Us page.

Do you want to do your own research on what size might be better for you?
Then this page is for you. Start by doing two things:
1) First assess your own sound profile.
2) Then ask yourself what you would like to get from a new mouthpiece. The big three seem to be better range, greater endurance, and a different or generally improved sound.

Assessing Your Sound Profile

You will find that we talk a lot about range and endurance in this fitting guide. Why do we focus on them so much? It is because range and endurance are the two things most players say they are looking for in a new mouthpiece. The key is to improve range and endurance along with getting a better sound. Although they can be addressed separately, range and endurance are often linked. Range becomes much bigger issue when we are tired. That, basically, is the definition of endurance.  
You can get good information about possible ways to improve your range and endurance by doing an honest assessment of your sound. That means asking yourself if your sound quality in all registers is ideal or at least acceptable, and if your range is ideal or at least acceptable.

Most players have one of the following three sound profiles, and very few have the "Ideal Sound Profile".

1) Do you have a "Pyramid Sound Profile"?

The most common problem players report to us is a sound that is big and fat in the mid to low register, but small, strained, and limited in the upper register. Their sound is shaped like a pyramid. It has a broad base, but does not extend as high as they would like, as depicted in the "Pyramid Sound Profile" graphic. Compare the breadth of sound between the lower and upper register, and note their range.
You can see that there is an imbalance. The sound is broader than what is expected or required, and their range is not optimal or even acceptable.

2) Do you have an "Ideal Sound Profile"?

A far more desirable sound profile is shown in the "Ideal Sound Profile" graphic. The breadth of sound and range are both in the ideal range.

3) Do you have a "Balanced Sound Profile"?

Unfortunately, there are few things that are ideal when it comes to brass playing, and especially when it comes to mouthpiece selection. Rather than playing the "perfect" mouthpiece we play the best mouthpiece possible based on a series of decisions we make and compromises we accept in the playing characteristics of a mouthpiece. Our goal should be to arrive at the best balance of sound and other playing attributes in a mouthpiece. The result is a sound profile that looks like the "Balanced Sound Profile" graphic.
Players switching to a Wedge mouthpiece will often get a more even response between the registers. In many cases players with a pyramid sound profile can balance their sound even more with a slightly smaller mouthpiece.

I want better range and endurance without changing my sound.

Most players will get better range and endurance with a similar sound when they switch to a Wedge mouthpiece. However, range is usually more of an issue when you are tired compared to when you are fresh. For that reason a good way to get an extra boost in range is to try a mouthpiece with a similar cup depth and slightly smaller diameter. This is especially true if you are using a larger than average mouthpiece and if you have significant problems with range and endurance.
The smaller diameter will usually increase endurance, and therefore range when tired, without having making the sound significantly brighter. A smaller diameter has more of an effect of reshaping the sound, making it a little less broad at the base and bigger at the top. Imagine changing the shape of your sound from a broad based pyramid to a narrower, but still strong based column that reaches higher.

Choosing a Mouthpiece Based on Cup Depth

F Cup

  • Similar to a PT65 cup
  • Shallow, modified V shape
  • Excellent balance of clarity and projection
  • Even response in all registers and a round, full tone

G Cup

  • Similar to the Schilke Geib, Bach 7, Bach 12, and Yamaha 67C4 mouthpieces
  • Cup shape is a modified funnel, which is slightly more bowl shaped than a Helleberg style cup
  • Sounds is less dark than a Helleberg cup, with a bit more projection
  • Excellent choice for rotary valve tubas

H Cup

  • Helleberg style cup similar to the Schilke Helleberg II, Conn Helleberg, and Laskey H series mouthpieces
  • Deep funnel shape
  • Dark, round sound that still has excellent projection when desired

D Cup

  • The Wedge D cup has a deep bowl shape similar to the PT50 and PT88 mouthpieces.
  • In smaller diameter is an excellent choice for a player looking for the characteristics of a Bach 24AW on EEb tuba.
  • In larger diameters produces a huge sound with a very even response in all registers.

How Do I Know Which Wedge is Right For Me?

We offer American and European shank sizes. The challenge is in knowing what shank a particular tuba takes. Sometimes a customer will insist that since there tuba is made in Europe it must take a European shank. Unfortunately, it is not that simple. In order to try to make sense of the lack of standardization in tuba mouthpiece shank sizes we have gathered information from a variety of sources on the web and present it below. Diameters given are of the small end of the shank, and are approximate as they vary from between manufacturers.
**Pleast Note: Most tubas with a European receiver will accept an American shank mouthpiece, although some will “bottom out” on the leadpipe. However, pitch and slotting are often better with the correct shank. Tubas with an American Receiver will accept a European shanked mouthpiece, but the lack of correct penetration and increased gap will have also a deleterious effect on how it plays.
