This is a **"NOUVEAU 5M (Lightweight)" mouthpiece for large-bore tenor trombone** from GRIEGO. Retail Price: 36,850 yen 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 blow smoothly, the intonation is stable, and it's easy to use in various genres. For these reasons, I think it's a versatile model that can be used in a wide range of settings, such as orchestras, wind bands, and ensembles. I recommend it for 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 company's 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 or similar. 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.
