SLIDE TONE / STARLING SILVER / Full set for Tuba NachtmusiK BRASS FACTORY original, handmade acoustic adjustment rings for trumpets. These primarily alter the acoustics and playing feel. They increase resonance, allowing the sound to carry to the back of the hall. The instrument's response improves, allowing for finer control. The sensation of hitting high notes becomes better, and they are effective in expanding the range and reducing misnotes. These are not the conventional "mouthpiece rings" that fit on the mouthpiece, but a new type of acoustic adjustment ring that is attached to the slide parts, such as the main tuning slide. Used by Emmanuel Urso, principal solo horn player of the Orchestra of the Teatro alla Scala in Milan. A message from Mr. Urso is available on Instagram. https://www.instagram.com/reel/DFK9CM9s1dm/?utm_source=ig_web_copy_link&igsh=MzRlODBiNWFlZA== While many accessories are supervised by professionals, SLIDE TONE is a product that studies the resonance of materials from a scientific perspective, rather than relying on a professional's sense.
