Osmun horn mouthpieces are the result of many years of playing and working with horn players. A variety of cup and rim contours and widths enable every player to tailor a mouthpiece to his or her playing style, instrument, and environment. Our "Sound Family" concepts helps you know what to expect from a mouthpiece and clear diagrams show you how cups and rims compare.
Our metric rims measure 17.5mm where they meet the cup and have Paxman Halstead-Chidell .800"-36 threads. They fit our metric cups as well as those from Halstead-Chidell. Our rims are available in five inner diameters in .5mm increments from 17-19mm. Other sizes are available as special orders.
Our standard finish is gold over silver plate. Gold is hypo-allergenic, non-tarnishing, and feels soft and slippery on the embouchure. Delrin rims are temperature neutral and work well for players who use a dry embouchure. Our plated finishes are very durable and, with normal care, can be expected to last for several years of heavy use.
