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 resonance by the resistance caused by wearing 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 mouthpiece pipe, and the lost vibrational energy cannot be ignored. Returning this "loss" to the instrument body as much as possible. This is the effect of Re:VIBRATION. When worn, 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 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. Also, flexibility is created, and delicate expression becomes possible. Re:VIBRATION enhances the resonance itself while also bringing about good changes for the player. Revive. The vibration that returns to the body leads to the best performance. The material of many instruments is made of brass, and the "YELLOW BRASS model," which uses the same material as the instrument, is characterized by its natural feel when worn. Each metal has its own natural frequency (resonance frequency), and the damping behavior of vibration differs depending on the metal. In other words, there is a frequency that is easy to resonate with for each metal material. By using the same material as the instrument, it is expected to maximize the potential of the original instrument rather than creating a change in tone.
