When we have gazed at the beauty of some fish species, it is hardly imaginable, that there are so many more designs of the same basic pattern are existing, which are all different, but in the one case always closely correct.
The reason for this brilliancy is maybe a great composer, who creates from one motive many variations, each with its own beauty.
