I am currently working on a project characterizing the materials used for concertina reeds. I know that brass is considered more traditional but that it has problems with cracking due to work hardening, and that steel is the most common now. But that is about all the information I've been able to find. Does anyone know of any other materials that are used for reeds or why these materials work? Is there something in the properties of the material that affects tone? I'd appreciate any information anyone has on this subject.
