Very good examples...Thanks....
I will put Scriabin juggling with tonal and atonal borders as another example of supreme creativity ...
some of my most interesting experiences were in hearing a piece for the first time that confounded expectations. When I heard the first moveemnt of Bartoks Music For Strings, Percussion and Celesta, the strands of music that seem to have a vague emptiness suddenly coalesce into a shattering climax that left me breathless because while it did germinate from the original seeds, it did in a way that was so unexpected that it startled. in a lesser way Mozart continually confounded his contemporaries by having his music go in directions that no contemporaries could pmatch, but always managing to make it seem a natural outgrowth of what had come previously. Mozart is just as origian las Bartok, but the Bartok seems more daring because our brains haven’t prepared us for what happens next
