Some music can come from nature: Birds.
Most species will only sing the exact same melody.
But some birds can sing upwards of 90 or more different songs.
Some birds can emit 3 seperate notes simultaneously.
And some very few birds can be incredible.
I've heard what I thought was a flock of birds, looked out the window, and discoverd it was a single bird . . . .
And not all of the birds of any given species (or flock) will sing the same.
Some birds have simple songs, while other birds, in the same flock, are just . . . incredible.
I have lived in rural areas all my life, and heard literaly, millions of bird calls.
There are bird calls, - and bird songs. There is a huge difference . . .
I have heard perhaps 100 - 150 'talented' birds.
.
They sing at dawn, and create new and wonderful melodies. They add and subtract notes from their melodies, improving their compositions. I've heard compositions of over 30 notes. They're fast, and many of the notes are above the average person's hearing range . . .
.
Most birds are average, but a very, very few are musical genious's.
I have heard three birds, in my 54 years, that were'world-class' composers. Just beautiful . . . phenomenal songs . . .
I heard the first one when I was about 26-27 years old.
Some of the compositions I heard were the main theme's in some of Bach's, Beethoven's, and Strauss's music - no joke.
. . . there is something implied there . . .
These birds listen to each other, and borrow 'riffs' from each other, adding and subtracting elements of their songs to improve the songs.
Some of it is hauntingly beautiful . . .
.
I suspect that many people have yet to hear this . . .
Again, I heard my first one when I was about 26 years old, and 've lived near broad expanses of fields and/or trees most of my life . . .
.
My genre of choice back then was hard rock, but this stuff was so beautiful it made my eyes water . . .
.
I guess this is the spot where the younger musicians all laugh at me and call me a talentless fool . . .
I don't care.

It's true; I've heard it; and I hope to God I hear it again, sometime before I die . . .
OK, now you can all go ahead and make fun of me . . .
