If only those who have made millions from the music industry were to bequeath what would be, for them, a trifling some, combined with income from recitals, there could be a living museum of individual instruments which have either historical significance, or represent the best of their kind. The other travesty is instruments/art held in a vault for no other purpose but to sell at a later date - only ever seen for a day or so every few years when it is on display at an auction house. - for the rest of the time it might just as well be firewood/scrap paper.
