It is worth mentioning that the collection of sounds that we use for music were rather arbitrarily selected, as are the rules and theories by which it is arranged.

Furthermore, the "music" that we and others create from them is appealing to us primarily because we are familiar with it, and understand how it is used to express things.

An analogy would be to our beloved English language, which is a closed collection of phonemes and morphemes that have specific meanings attached,and are organized according to strict rules of grammar to convey the full range of human feelings, ideas, and information.

Even so, it is an arbitrary contrivance, with meaning a product of familiarity and shared understanding, rather than any intrinsic qualities of either the sounds and words, or of the grammatical rules.

Just as Urdu, Arabic, Mandarin Chinese, and other profoundly different and mutually incomprehensible languages have the same capacity for summing up the human experience, there are other systems of sound and rhythm that can be creatively used to express the parameters of the human spirit.

Undoubtably, there are many places on Earth where people listen to, say, YouTube clips of the Watersons, and ask if it is music at all...
