That pure, instrumental music is the most direct, influential, and powerful music communicating immediately and deeply affecting the feelings of people round the world. Without the need for spoken language. Without the need for any advance specialized introduction or training.
I should add that these affects are equally evoked by electronic music and instrumental music of other cultures, as in the Indian sitar-playing of Ravi Shankar. Again, pure music/music at its purest. The best of pure music transcends Time and place.
