I am a professional trumpet player getting ready for my first backpacking trip. I'm equipped with a plastic trumpet that I'll clip on my pack. Now I'm starting to wonder about the best way to keep my chops in shape. I plan on only playing music and etudes, maybe at the end of the day before dinner and after setting up camp. Is this sort of thing acceptable, for example within campground rules? I know how far a trumpet can carry in the wilderness (especially across bodies of water) and would not want to upset other backpackers in the area.

Further, how can I best approach practicing while on the trail? What is customary and generally accepted about artificial noise on the trail? Any thoughts or advice would be greatly appreciated.
