I live in South Florida, in western central Broward County, where the city of Plantation meets the city of Sunrise. To the west is the Everglades, through which Alligator Alley runs, and to the south is Homestead Air Force base, both of which are known areas that have attracted UFO activity in the past.
The Hum
I walk my dogs every night and being somewhat of an amateur astronomer, I have a tendency to look up into the night sky. On clear nights, many stars and a few planets are visible. Sometimes planes circle around to land at Ft. Lauderdale Airport from the west. It’s usually quiet except for a low drone of cars on the Sawgrass Expressway.
One night at about 4am, I got up to use the restroom. The window that faces north was open about an inch. I decided to take a look outside through the crack in the window. Everything was still, no cars, no croaking toads and no planes (not at that hour.) As I got closer to the window, I began to hear a low hum that I thought was the wind in the distance, but then I started to hear musical tones over the low hum. I would compare it to “overtone singing” or “throat singing”, where a person is able to make two different sounds at the same time.
This was a constant low hum, not wavering in tone, and three musical tones on top of the hum. This was clearly not music playing somewhere and it wasn't the sound of cars in the distance; it was definitely a hum, definitely not human but almost mechanical sounding, and it kept repeating the tonal pattern. In musical notation it would be Do - Mi – Fa, then it would stop for a moment, then it would start again, and it kept repeating this same exact pattern, slowly and breathy, as if the wind was making the sounds.
I opened the window more to look around and to look up into the sky but I didn't see anything. I kept listening and the hum/tones continued for as long as I stood at the window. I was mesmerized and terrified at the same time. I finally realized I needed to go back to bed. Every night since then, when I walk the dogs I watch the sky and listen for the sound but I have never heard it again.
The reason I thought it might be a UFO-related encounter is because math and music are universal communication tools and it reminded me of the movie Close Encounters, where they used Curwen's hand signals to represent the musical tones that allowed them to communicate with the aliens.
