At work tonight there was this moment where I had to stand in front of the compost compactor and wait while it mashed together all the stuff inside so there’d be space for my compost bag (since the last person there neglected to activate it before they left -_-; ). When the compactor is active, it makes this constant noise in the form of a long tone at a moderately high pitch.
Since I was bored and had nothing else to do as I stood there waiting, I started humming along matching the tone. Which is to say I was just humming one long note of course.
But soon I got bored of just doing that, so I decided to see if I could adjust my pitch just enough to create a dissonance effect. I was successful, which made me grin to myself.
Clearly I still have some music nerd left in me from high school.
