原文にRESONANCEとあるので自分で訳してくれ

BRASS BELL
The high-quality brass bell is made of the same material as used on Yamaha's acoustic saxophone. Drawing on our extensive know-how and experience of making acoustic instruments, we designed this bell to gorgeously reproduce the long reverberation peculiar to wind instruments as well as the delicate sonic nuances sounds when playing pianissimo. Moreover, the authentic RESONANCE causes the entire instrument to vibrate, and lets you truly feel the music as you play it.
