Can attest to this.
An engineering analysis of the tones concludes that the singing noise comprises a variety of Aeolian tones (the sound produced by air flowing past a sharp edge), arising in this case from the ambient wind blowing across metal slats of the newly installed sidewalk railings.[ The tones observed were frequencies of 354, 398, 439 and 481 Hz, corresponding to the musical notes F4, G4, A4, and B4; these notes form an F Lydian tetrachord. #music
@constantorbit this is amazing! Reminds me of Thoreau in Walden: "when the wind was favorable, a faint, sweet, and, as it were, natural melody, worth importing into the wilderness. At a sufficient distance over the woods this sound acquires a certain vibratory hum, as if the pine needles in the horizon were the strings of a harp which it swept. All sound heard at the greatest possible distance produces one and the same effect, a vibration of the universal lyre"
@constantorbit@hachyderm.io@nathanlovestrees I love that quote. 
Really resonates with me.
(Man, I really need to read Walden. Stupid that I haven't yet. I also lived near his stomping grounds for decades.) (My ex and I used to stop by #waldenPond to go swimming after work.)
