Calm down, Nick! I thought I'd stated it quite clearly. I certainly can't think how I could make it any clearer.
Yes, of course much the same could be said of other works of art. It goes without saying, one would have thought.
But, unfortunately and obviously, most of the "great" composers (especially those of the Classical era) thought the organ not really worthy of their efforts, alas. The repertoire of our instrument would probably be much richer had they thought differently.
