Orchestral Mouthpiece with Plenty of Volume and Focus
Do you need an orchestra-style sound with enough projection and volume to cut through the mix? Then you’ve come to the right place. Yamaha’s 14A4a has a heavyweight outer profile, which adds extra mass to the outside of the mouthpiece for a concentrated sound. That said, it has the same internal dimensions as the standard 14A4a. The mouthpiece strikes a happy medium between focus and power, giving you a wonderfully expressive sound to work with. Sweetwater knows how vital your tone is to you, which is why we asked Yamaha about the specific characteristics of this mouthpiece. Yamaha informed us that this mouthpiece is designed for outstanding facility and flexibility, which is why it’s so popular in ensembles and orchestras.

Designed with professionals in mind

Professional symphonic and orchestra players require a tone that’s entirely separate from jazz and big band players. Yamaha GP Series trumpet mouthpieces feature specialized design elements that give players the feel, response, and tone needed to fit in with the world’s most famous orchestras. Most noticeable is the redesigned outer profile. The extra external mass works to darken and focus the tone into a formidable sonic weapon. Next, each GP Series mouthpiece has an extra-heavy gold-plated cup and rim. Gold plating does not meaningfully impact the sound. Instead, a gold-plated mouthpiece provides a smoother feel that some players prefer over silver. Players who prefer a more concentrated sound will love Yamaha GP Series trumpet mouthpieces.

Yamaha: the gold standard

Whether they’re building motorcycles, microchips, or marimbas, Yamaha’s commitment to quality is unmatched. And there’s no product category that exemplifies the Yamaha difference other than the brass instruments. Yamaha horns feature thoughtful and innovative engineering. Each one is subject to the strictest quality control measures before being released from their workshop. Yet, to be deemed truly excellent by Yamaha, these masterfully crafted pieces of art must light a fire of joy and passion in the player’s heart. Whichever Yamaha horn you choose, you can expect it to live up to those lofty expectations.
