Thank you for viewing! This is an authorized dealer of NachtmusiK BRASS FACTORY. It effectively returns the vibrational energy lost from the outside of the mouthpiece back to the instrument. The ring part, made as thin and small as possible, does not stress the instrument. Many mouthpiece rings change the playing feel and control the sound by the resistance caused by attaching them. Re:VIBRATION focuses on "lost energy" instead of resistance. Mouthpieces designed for removal have a tapered structure with a small connection point to the mouthpipe, and the lost vibrational energy cannot be ignored. This is the effect of Re:VIBRATION: to return this "loss" to the instrument body as much as possible. When attached, you will feel the difference in resonance and vibration from your hands, lips, and ears. This sometimes gives the player power and sometimes frees the player from excessive tension and stress. "Not tensing up" is an important issue that is directly related to all problems. Re:VIBRATION leads to the solution of the most important issue. By not tensing up, high notes become easier, fortissimo becomes stable, and the tone improves beautifully. It also provides flexibility and allows for delicate expression. Re:VIBRATION enhances the resonance itself while also bringing about positive changes for the player. Revive. The vibration that returns to the body leads to the best performance. COPPER BRASS improves the playing feel and changes the sound to a deeper, more lustrous resonance.
