2b heli good music (to my ears)

Video is a still image.
Audio is from a helicopter passing overhead, slowed from 2 seconds to 2 minutes using Audacity's Change Tempo with high quality stretching, first to get it to 40 seconds and then to the full 2 minutes. I did not add any music, but it has a musical quality to it. I think this is possibly due to either (a) the nearby windchime on the opposite corner of the porch from the microphone, or (b) the jingle my camera played at the end of a high frame rate recording (which I was originally trying to match when I created this audio, although it would need to be 40x not 60x to match and I wasn't finding a proper alignment with the video, but decided this sounded nice and should be uploaded.)
Audio recorded July 2, edited July 3-4 2020.
