This is a **"NOUVEAU 5M (Lightweight)" mouthpiece for large-bore tenor trombone** from GRIEGO. Retail Price: ¥36,850 This mouthpiece has a very well-balanced overall feel, with a quick response and a straightforward, direct blowing sensation. Although it's a lightweight model, the sound doesn't become too thin, and it still provides the necessary volume and core. It's easy to use in a wide range of situations, such as: * Easy to breathe into * Stable intonation * Versatile and suitable for various genres From these points, I think it's a model that is easy to use in a wide range of settings, such as orchestras, wind ensembles, and chamber music. I recommend it to those who want to pay attention to subtle nuances in their performance, those who use instruments with lighter (thinner) bells, and those who find the W-brand Valkyrie model a bit lacking. It seems to fit European instruments, as well as general large-bore tenor trombones like Yamaha, without any problems. ⸻ Specifications • Cup Inner Diameter: Approximately 25.50mm • Throat Diameter: Approximately 7.09mm • Lightweight Specification • Finish: Silver Plated ⸻ Recommended for those who: • Are looking for an easy-to-blow and easy-to-handle mouthpiece • Find a size around 5G suitable • Want to try GRIEGO for the first time In terms of blowing feel and size, it's easy to transition to for those who are using Greg Black 5G size. I think it's also a good model for those who are looking for better responsiveness and lightness, based on the solid core of Greg Black.
