Choosing The Right Mouthpiece

What is a facing?

Each model of the Reserve mouthpiece is named for its facing, which measures the curve of the mouthpiece away from the reed.

A facing is often identified by its tip opening: the distance in mm between the reed and the tip of the mouthpiece.

Choose a closer facing (smaller tip opening) for less resistance. Closer facings generally require the use of harder reeds.

Choose an open facing (larger tip opening) for more resistance. More open facings generally require the use of softer reeds.

The Mouthpiece Test


When testing mouthpieces, personally or with students, you should first listen for a comfortable, free response. Play a slow scale or passage, both slurred and articulated.

Is the sound produced easily? Is it possible to slur and articulate clearly, without struggle?

If the response is too difficult, consider trying a closer (less resistant) mouthpiece facing, or a lower strength reed.

If the response is too easy, consider trying a more open (more resistant) mouthpiece facing, or a higher strength reed.


Next, consider the core and quality of the sound. It's important not to sacrifice a centered sound for ease of response. Both attributes are possible, with the correct marriage of reed strength and mouthpiece facing.

If the sound is spread or lacks center, consider trying a higher strength reed or a more open (more resistant mouthpiece facing).

The Patch

The Reserve mouthpiece patch protects the mouthpiece, prevents the teeth from sliding, and prevents biting. Our unique material adheres securely to the mouthpiece, yet enables easy removal or transferal when needed; it will not leave residue.

To Apply

Simply peel the patch from the sheet and place firmly on the mouthpiece, being sure to leave a small amount of space between the patch and the tip of the mouthpiece.

Teacher Tip

Cutting a patch in half or placing a patch further down on the mouthpiece can be a great tactile reminder for students of where to put their teeth and of how much mouthpiece to take. This can help combat a frequent issue for developing clarinetists: failure to take enough mouthpiece in order to produce a full, centered sound.

"The Reserve mouthpiece has raised the bar. D'Addario has succeeded in designing a mouthpiece that sounds like the great vintage mouthpieces of old, has superb intonation and articulation, and gives the player huge satisfaction; at only a small fraction of the cost!"
Richie Hawley, Professor of Clarinet, Shepherd School of Music | Rice University (Houston, TX)
"The Reserve mouthpiece is the best mouthpiece that I have every played! It allows me to produce a velvety rich sound that has diamond-like shimmering core. It makes all other mouthpieces feel simple and two dimensional."
Lee Livengood, Utah Symphony
"The Reserve mouthpiece will help clarinetists play with ease and beauty, and will open the door to wonderfully expressive music making."
Sasha Potiomkin, Acting Bass Clarinet, Houston Symphony
"I am very impressed with the new line of the D'Addario clarinet mouthpieces. I tested them successfully in orchestra and with my students. The response and intonation are great, as well as a consistency from mouthpiece to mouthpiece. I can see it working for many players, professionals and students alike."
J. Lawrie Bloom, Clarinet/Bass Clarinet, Chicago Symphony
"I am so pleased with the results of the new Reserve mouthpiece by D'Addario. With this mouthpiece I feel I can achieve a deep, full and satisfying sound with great complexity and colors. A balanced combination of highs and lows allow easy projection without brittleness in the sound. I find the pitch in all registers exceptional and it is easy to match timbre from clarion to altissimo. All in all, I have found the Reserve an exceptional mouthpiece. The consistency is fantastic, so my spare feels like my #1, and my students can play an identical product. This is a huge step forward in the evolution of mouthpiece manufacturing."
Gary Whitman, Clarinet/Bass Clarinet, Fort Worth Symphony, Clarinet Faculty, Texas Christian University
"D'Addario's design research and attention to detail with the development of the Reserve mouthpiece has resulted in an ideal mouthpiece for depth of sound, tonal projection, and response in all registers. It can be used in a variety of venues, such as solo recitals, chamber music, and the orchestral stage."
Jonathan Gunn, Principal Clarinet, Cincinnati Symphony Orchestra
"When playing the new Reserve mouthpiece, it is immediately apparent that D'Addario has developed a winner. It is easy to play, produces a beautiful sound, and has great response in all registers. Everyone should try this new mouthpiece."
