The package contains 3 trumpet mouthpieces (1x 7C, 1x 5C, 1x 3C) and 1 Trumpet Mute Silencer. The set can meet the needs of different occasions and learning stages for the player. It would be a great gift choice for friends or children.

The sizes 7C, 5C, and 3C range from small to large, including the outer rim, inner cup, inner diameter, and inner tube, all of which are from small to large. These size changes are very small, difficult to distinguish with the naked eye.

The 7C mouthpiece is suitable for beginners or children with small lips, as the structure of the 7C mouthpiece is relatively small, making it easy to produce sound when playing and the high notes are easy to articulate. After some practice, the lip muscles become stronger, so you can consider switching to 5C and then to 3C.

3C is a more comfortable size for trumpet players (non-beginners). The cup of the 3C mouthpiece is relatively shallow compared to the cup of the larger size, which would improve the lips' reaction speed and make the high notes brighter.

The Trumpet Mute Silencer is made of aluminum alloy; Length: 135 mm; input diameter: 18.5 mm; output diameter: 61mm. Suitable for all types of trumpets; this aluminum mute has a pleasant sound and does not distort the pitch, you can enjoy your practice with this trumpet mute and your family members, neighbors, and pets will no longer be disturbed.
