How to Find the Best Trombone Mouthpiece

Are you having trouble getting the sound you want on your trombone? Before you shell out thousands for a new instrument, consider how to find the best trombone mouthpiece.

Sometimes, a new accessory is all you need to improve your playing. Not only can you save money now, but you may be able to play your current instrument for many more years.

Trombone Mouthpiece Anatomy

One of the first steps for how to find the best trombone mouthpiece is to understand the anatomy of a mouthpiece. Then, you can understand how to compare mouthpieces to choose the right one for you.

While you can find mouthpieces using silver, gold, or other metals, they all have the same parts. Here’s what goes into a good trombone mouthpiece.


The cup is the area of the mouthpiece you blow into when playing the trombone. Smaller cups are great for beginners because they don’t take as much stamina to get a good sound.

Bigger cups are more flexible, and they can provide a deeper tone. As you advance, you may choose to upgrade to a mouthpiece with a larger cup.


Around the cup, you’ll find the rim of the mouthpiece, and you can find rims with a flat or rounded contour. Flat rims seal evenly against your lips, and they’re comfortable to play with.

However, rounded rims let your lips move more to produce different tone colors. They’re better for players with experience because they require strong lip muscles to maintain more pressure.


Once your air goes through the cup, it will pass through the backbore before entering your instrument. The shape and size of this part can affect the dynamics and tone colors that you can play.

If you’re new to playing the trombone, you should look for a backbore that’s not too big or small. That way, you’ll get a good about of flexibility and control, but you won’t need to work super hard to play.


Between the cup and the backbore, you’ll find the throat of the mouthpiece. Throats don’t vary in size that much, but you can find bigger ones that let you play louder.

The main purpose of the throat is to connect the cup and backbore to help offer good projection and tone. That way, you can get a good sound on your trombone.

How To Find The Best Trombone Mouthpiece

Once you understand the trombone mouthpiece’s anatomy, you can figure out how to find the best trombone mouthpiece for you. You can find tons of models available, and some may play better for you than others.

So while you can get recommendations, other players may suggest mouthpieces that won’t work for you. Instead, follow these steps to shop for and buy the right gear based on your playing.

Know Your Trombone

You should know what type of trombone you have, both in terms of the size and the brand. When it comes to the size, you can make sure to choose a mouthpiece that will fit your instrument.


A tenor trombone mouthpiece won’t work with a bass trombone mouthpiece or vice versa. But trombone brands can also come into play in finding one that matches well.

For example, if you play a Yamaha trombone, you might want to start by looking at Yamaha mouthpieces. Then, you can look at other brands if that setup doesn’t work.

Test Your Current Mouthpiece

Another thing to do before going shopping for new equipment is test what you have already. Consider if you really need a new mouthpiece or if your current one works fine.

Think about if you want to get a different sound or if your current mouthpiece is holding you back in another way. Those are both great reasons to upgrade.

However, if you just want a new accessory to have something new, maybe hold off. Then, you won’t pay a ton of money and end up having buyer’s remorse.

Consider Your Budget

If you do need to get a new piece of gear, think about what you want to spend. You can find mouthpieces for less than $50 and others for more than $200.

Having a budget can help narrow your search, and it can give you a chance to save up for the purchase. Then, you don’t have to finance the mouthpiece or get one that doesn’t meet all of your needs.

If you don’t like the options in your budget, you can save up a bit more. That way, you’ll have more choices, and you can keep looking for the right mouthpiece for you.

Think About The Genre

The trombone is equally popular within classical and jazz music. But each genre requires a slightly different playing style, and having the required equipment can help you play each type of music.

If you only play classical music, you may want to get something with a softer tone. On the other hand, jazz requires a bit more oomph, so you might want a different setup.

Players who perform both classical and jazz can get a mouthpiece that works for both. Or you can consider getting one mouthpiece of classical and another for jazz.

Avoid Cheap Brands

When shopping for music equipment, especially online, you may come across a lot of cheap options. However, these “affordable” models can be a waste of money.

They usually aren’t made of the best quality, so you can’t expect them to last a long time. Over a few years, you might spend more buying multiple cheap mouthpieces than spending more on one.

Instead, stick to well-known brands, like Bach and Yamaha. That way, you’ll know you’ll get a good-quality product that will last you for years.

Use Your Trombone

When you’re ready to buy a mouthpiece, you should test it out before committing to the purchase. To keep the test of each mouthpiece as far as possible, use your current trombone.

Trombone 1

Don’t switch instruments to play a different mouthpiece. Doing that will add another factor to the test, so you might not be able to decide which accessory is the best for you.

Using your trombone will also help you understand how you can expect the instrument to play. That way, it will be easier to tell if one mouthpiece is more resistant than another.

Select Diverse Repertoire

Along with using your trombone, you should use some music or excerpts to test and compare mouthpieces. Make sure you use the same pieces with each setup to determine which sound and feel you like the best.

Choose pieces that cover the full range of dynamics so that you can play loud and soft. Look for both fast and low pieces to test how it feels to play technically and lyrically.

You should also test using music that’s both low and high. While one mouthpiece might sound good in the low register, playing higher notes could be difficult, and you need to minimize any post-purchase surprises.

Record, Listen, Repeat

Another crucial part of how to find the best trombone mouthpiece is recording yourself. Use your phone or a separate audio recording device while you play each trombone and mouthpiece combination.

Then, you can listen back after each trial to see how the setup sounds as a listener. Take written notes about the sound and feel of each trial, especially if you can’t try a ton of mouthpieces back to back.

Record each trial and compare them before you buy anything. That way, you’ll have more information to help you choose the right gear for you and your playing.

The Best Trombone Mouthpieces

While every trombonist needs a different setup, you should have somewhere to start when upgrading your gear. There are a few well-known brands with fantastic mouthpiece models to try.

Answer: The way you choose a mouthpiece for your trombone depends on a lot of factors. You have to consider the size and type of your instrument, your playing level, and your budget.
Once you determine those things, you should test as many options as you can. Compare them to figure out which you like best, and you can buy that one.

Question: What does small and large shank mean?

Answer: Small and large shanks refer to the size of the end of the mouthpiece that connects to the trombone. You should consider if your instrument can connect to a small or large shank.
Then, you won’t waste time or money trying mouthpieces that won’t even go into your instrument. Consider asking a teacher or instrument repair technician to help measure your trombone’s bore.

Question: Does the mouthpiece really affect your sound?

Answer: Your trombone mouthpiece can have an impact on the sound of your instrument. If you get a bigger mouthpiece, you may have more flexibility, and you can play louder.

Question: Can you use a trombone mouthpiece on other instruments?

Answer: Some trombone mouthpieces also work on other instruments, like euphoniums or baritone horns. If you want a mouthpiece that works on multiple instruments, bring them all when you test out the accessory.
That way, you can make sure the setup will work where you need it to. You can look at the product description, but it’s worth testing the gear in real life.

Question: How much does a trombone mouthpiece cost?

Answer: Trombone mouthpieces can cost as little as $40 or more than $150 to $200. The cost depends on the materials, brand, and other factors.
