This pioneering bi-material mouthpiece with its unique acoustic and sound properties testifies to Henri SELMER Paris' ever-growing desire to improve its products. Designed in close collaboration with Claude Delangle, this mouthpiece perfectly reflects his personality. A remarkable demonstration of our expertise, the Claude Delangle mouthpiece emphasizes the importance of creativity in the search for sonic perfection while continuing and reinforcing the long Henri SELMER Paris tradition. The metal ring characteristic of Adolphe Sax's first mouthpieces and its cutaway design testify to a privileged relationship between tradition and the latest advances of the Concept family. The gold-plated metal ring lines the entire bore and allows for a denser, fuller sound with increased projection. The acoustic performance of this new alto saxophone mouthpiece signed «Claude Delangle» will charm saxophone players and audience members alike.
