The YAMAHA YTR 6310 Z Bobby Shew 3 Bb Trumpet is tailored for jazz musicians, delivering remarkable lightness and ease of play. Made in Japan, it features a yellow brass bell with a diameter of 5 inches (127 mm) and a small bore size of 0.445 inches (11.30 mm), giving it unique characteristics.

This trumpet is perfect for all sizes of players, thanks to its small bore which offers optimal playing comfort, especially for young musicians. Its build quality is exemplary, with consistent production and appreciable aging capacity.

Despite its small bore, the YTR 6310Z produces a wide and powerful sound, competing with more standard-sized models like the 6335. However, a few points should be considered. The sound color of this trumpet may seem "flat," lacking a distinctive sonic identity, neither too bright nor too dark. Additionally, the provided case, though sturdy and aesthetic, is not particularly practical.

It is also important to note that the projection of the YTR 6310Z is relatively limited compared to its competitors, making it less suitable for large ensembles or orchestras. Finally, this model may be considered expensive compared to other available options on the market.
