Great article indeed!
I'll however disagree on a slight detail point : a true sensible and contemplative mountaineer would not make the same choices as quoted in Bernard's article when it comes to carrying a grand piano, and will much more likely carry a harpsichord, first because it's lighter than a grand piano and second and mostly because Bach wrote many more fugues for it than he wrote for the piano(forte) (and an organ may be a bit too delicate an instrument to bring with, not to mention the wind drag on a stormy ridge).
