High quality: Our trumpet mouthpieces are made of brass, offering a comfortable touch and excellent sound. The silver plating ensures durability and makes cleaning easy. Value Pack: This package includes 3 trumpet mouthpieces (1 x 7C, 1 x 5C, 1 x 3C). This variety supports different playing needs and skill development. Precise Size: The set includes three mouthpiece sizes, ranging from small to large, with precise specifications for outer rim, cup depth, inner diameter, and backbore. Engraved markings allow for quick and easy identification of each type. For beginners, the 7C is recommended as it is easier to produce a sound. As lip strength and technique improve with practice, players may transition to the 5C and eventually the 3C, which is commonly used by advanced and professional players. Application: These mouthpieces are compatible with most standard trumpets and suitable for various settings, including school, concerts, home practice, band rehearsals, and more.
