I can hear Shepard tones [1] in songs now. I remember the first time I heard it in a song, I was blown away, confused as to what I was hearing.

Later when it was pointed out to me that is is "a thing" I started to recognize them in other songs. I sort of miss being naive.

There's a line from one of Feynman's books where he is arguing with an artist friend who dislikes how Feynman (science generally) dissect a rose rather than just admiring its beauty. Feynman is incredulous as to how knowing more about a thing can take away from its beauty. (I may be slightly mis-remembering this exchange.)

That always bothered me because I felt that naïveté is a thing you lose with knowledge and that is not always a good thing.

Walt Whitman's "When I Heard the Learn’d Astronomer" [2] instead resonated with me.

Shepard tone is popular for building suspense. The soundtrack for the movie "Dunkirk" leverages a pretty identfiable shepard tone for anyone interested in hearing a quick example.


First one I heard was in an obscure song by an obscure band, O Positive and their song (appropriately titled, "Up Up Up" — closes at around 3:00):

There's an Elliot Smith song with it as well ... I'll have to try to recall it.



One's a sensation, the other is a mental model of the sensation. Big difference.

You can direct your attention at one or the other. Maybe both to a degree but concentrated deep focus demands exclusivity.
