When AR Resonance started in 2014, we wanted to build a mouthpiece that sounded like the best we ever heard while still being extremely easy to play. The founding concept of all Resonance mouthpieces is to offer the player a back pressure level and the harmonic spread that their body and his skills demand.

We DON'T want the player to acclimate to our mouthpiece, we want to serve the player with the best solution they feel to be the right one.

We've been through all that crazy stuff and we concluded we must not be told what to think, do or feel, we want to be in control.​

E = Shallow, not a lead cup but almost

LEAD = Shallower but not crazy shallow, for lead work

LEAD PLUS = for hard core lead players

Everything plays a role in a mouthpiece and weight and its distribution is one of the key elements. We prefer to avoid any kind of unbalance as the "player-mouthpiece-trumpet" system has to resonate as a single element. You wouldn't want to run with moon boots or swim with a big hat, would you?

Let's keep it reasonable, your lips will thank you!

While we can customize anything, we have found that almost all of our clients have had extreme success playing either our 40 or 42 throats.
They stand for 4.00 and 4.20 millimiters, roughly #21 and #19 in american sizes. While we think a larger than usual throat is needed to offer a much better sound and perfect intonation we are aware trumpet player are human beings and not aliens!

We don't want you to have to acclimate to our product, they will feel better right away!
