To produce a rich, harmonic sound, not only the breath within the instrument but also the resonance of the instrument itself is an important factor. Many professional players believe that one-piece bells are superior to bell-cut bells in French horns. This indicates that the joints of the instrument can cause a loss of resonance. Among these, the joint between the mouthpiece and the mouthpipe is the part of the instrument that loses the most resonance. This product was born from the concept of efficiently returning the untransmitted vibrational energy and the vibrational energy radiating outward from the mouthpiece to the instrument, preventing the escape of vibrational energy. The effects are like: sounding further, and creating a core in the tone. It may also make it easier to hit notes that are difficult to hit (such as high notes). It may also lead to improvements in the instrument's unique characteristics. *This product does not compensate for the technique of beginners. All manufacturing processes are handmade.
