A group of connected keys may be made in one piece during this method. Alternately, particular person keys may be stamped outby a heavy stamping computer, and then trimmed. These particular person keys are then soldered along with silver solder to make the attached group. Next the keys are polished. Keys for within your budget models may be placed in a tumbling computer, where friction and agitation of pellets in a revolving drum polish the pieces. More expensive keys may be buffed in my opinion by being held against the rotating wheel of a polishing desktop. Some keys may be silver plated, after which polished. Clarinet production itself is a reasonably conservative industry, counting on highly skilled craftspeople who do much work by hand. Most of the concepts in clarinet design are now 100 years old. One area that is still in flux, even though, is the manufacture of clarinet reeds. While one of the best reeds are said to come from a species of cane grown in France, some players and makers are experimenting with wild cane that grows in California.
