gravity has played a big part in music, so this is not so far removed. I love the unexpectedness of the project, and hearing a familiar melody ( one of my favorites ) in an unusual rendering adds a sense of discovery. It is both familiar and surprising.
There are wind chimes in my neighborhood, and I enjoy that too. Water in streams makes sounds with the help of gravity. Music as we know it began with natural sounds and natural materials.
