The long-established firm Henri Selmer Paris has developed an alto saxophone mouthpiece in collaboration with Professor Claude Delangle, which is characterised by superb projection and a full tone. The rubber mouthpiece is based on Selmer’s Concept series. The gold-plated metal ring merges into the rail. This gives the Selmer ‘Claude Delangle’ model its precise response and centred, full tone. The bore opening is 1.65 mm and the bore length is 24 mm. The chamber is round in shape. A mouthpiece for the discerning alto saxophonist.
