I have to swab out the trumpet, a task I defer as long as possible, because all of those broken notes and things will eventually affect the its dulcet tones. And as for "organic" mouthpieces, you can only say that if you play double reed, like a (shudder!) oboe. A clarinet mouthpiece, for example, is mostly plastic or ebonite or something, and only the vibrating reed (once a living thing and then cruelly plucked and viciously split) could be called "organic." In the interests of preserving the environment and the living things around us, trumpeters can use THEIR mouthpieces for years and years.
