As a reasonable fiddle player without any particular talent or genius, it really saddens me to see beautiful and valuable violins displayed in glass cases in museums.

Just let me, or any other half-decent fiddle player, play that violin for one evening at a local folk club, or with an amateur orchestra! Even with our blunders, we'd give people far more pleasure than can ever be achieved by displaying that beautiful instrument as an untouchable historic artefact for tourists to gaze at!

I'm sure the same is true of many other musical instruments.
