Music the Most Perfect Communication?

Jonathan Edwards, from Miscellanies #188:

The best, most beautiful, and most perfect way that we have of expressing a sweet concord of mind to each other, is by music. When I would form in my mind an idea of a society in the highest degree happy, I think of them as expressing their love, their joy, and the inward concord and harmony and spiritual beauty of their souls by sweetly singing to each other.

Do you think he's right? Why or why not?
