One of my grandmother's antique clocks being wound up a couple times - gives a low, twangy chime. You can also hear the pendulum ticking and the wind up of the chime. Recorded on a sony pcm-d50.
The sound started as a drop of water in a pot filled with water. I then slowed it down significantly. It startet to sound quite melodic like a chime. I added some reverb and echo and thats what came out.
Shortened a glockenspiel chime by angstrom (https://freesound. Org/people/angstrom/packs/583/) to approx 1 second duration for use in a coding exercise/game.
