Trumpet mouthpiece MR3 lightweight with resonator

The Padovani Music MR3 Light Mouthpiece with Resonator was developed for musicians looking for strong rim support, comfort, projection, and a fast, centered response, in a more compact size within the MR line.

The main characteristic of the MR line is its wide, rounded rim, which is the widest rim among Padovani Music's conventional trumpet mouthpiece lines. This larger contact surface distributes the pressure of the mouthpiece against the lips over a wider area, providing a greater sense of support and comfort for many players.

Because of this characteristic, the MR3 is especially recommended for players who prefer substantial rim support while playing. Musicians who prefer a narrower rim, with greater freedom for embouchure movement and a more defined contact sensation, may adapt better to other lines such as the M or S.

The inner edge of the rim also features a rounded profile. This allows the lips to enter slightly farther into the cup while playing, which can make the mouthpiece feel slightly smaller than its nominal inner diameter might suggest.

Its medium-shallow cup, combined with a smaller inner diameter than the MR1 and MR2 models, promotes a fast response, greater focus, and more ease in the upper register. The MR3 tends to deliver a bright, centered, and defined sound, while maintaining the characteristic rim support of the MR line.

This combination makes the MR3 an excellent choice for popular music, Salsa, Mariachi, Lead Trumpet, bands, and playing situations that require projection, definition, agility, and strong sound presence.

Resonator

Padovani Music resonators, available in several finishes, provide not only a distinctive visual appearance but also variations in tone and projection. The player can use the mouthpiece with or without the resonator, adjusting the sound according to personal preference and musical needs.

• ✅ With resonator: darker, smoother sound with more centered projection
• ❌ Without resonator: brighter tone with more open projection

What is the difference?

Compare the MR3 with other sizes in the Padovani Music MR line:

• 🔹 MR2 Light: has a larger inner diameter and greater cup volume. The MR2 offers more room for the embouchure and slightly more body in the sound, while the MR3 provides greater focus, a more immediate response, and more ease in the upper register.
• 🔹 MR5 Light: has a smaller inner diameter and lower cup volume. The MR5 tends to provide even greater ease in the upper register, more brightness, and a more compact embouchure feel, while the MR3 retains more internal space and a greater balance between sound body, projection, and ease of playing.
