I got a new (old) spinet. It was wildly out-of-tune. I hired the highest-rated piano tuner on Yelp. It was Alex who informed me my new piano wasn't a piano, but a spinet. He gave me permission to record him at work; and I made this "montage" out of the 3-hour recording. I think a 'bending' piano note is one of the weirdest-sounding things, and a single piano note suddenly getting louder is weird too, but in a more subtle way.
