SLIDE TONE / STARLING SILVER / 8mm for Horn NachtmusiK BRASS FACTORY original, handmade acoustic adjustment ring for trumpets. It mainly changes the sound and playing feel. It increases resonance and makes the sound reach the back of the hall. The instrument's response, which responds to subtle control, is improved. The sensation of hitting high notes becomes better, and it is effective in expanding the range and reducing mistones. This is a new type of acoustic adjustment ring that is not a "mouthpiece ring" that fits on the conventional mouthpiece, but is attached to the slide parts such as the main tube. Used by Emmanuel Urso, principal solo horn player of the Orchestra of the Teatro alla Scala, Milan. We are publishing a message from Mr. Urso on Instagram. https://www.instagram.com/reel/DFK9CM9s1dm/?utm_source=ig_web_copy_link&igsh=MzRlODBiNWFlZA== Many accessories are supervised by professionals, but SLIDE TONE is a product that studies the resonance of the material from a scientific perspective, rather than the professional's sense.
