Denis Wick Silver Plated Flugel Horn Mouthpieces. The true Flugelhorn sound is not to be found on any other brass instrument. By using very deep cups and carefully matching throats and backbores, Denis Wick has created a Flugelhorn tone quality that is possibly one of the most beautiful sounds ever made on a brass instrument. Flugelhorn players can now enjoy their own special sound with perfect intonation.
