It’s annoying to be told that you should listen to classical music just because. So I won’t do that. Instead I’ll recommended this particular song that happens to be categorized as classical. I do not listen to music like this much, nor do I seek it out, but sections of this song are in Tree of Life and that compelled me to listen to it in its entirety. The song is long and repetitive, but has an unpretentious and beautiful meditative quality to it. And it sounds as natural as the tide coming in and going out.
