A small but simple idea, the grandfather clock item should emit some sort of chime every hour, like real ones do. Just a little thing to add more to the ambience 
The westminster chimes are pretty popular for grandfather clocks, as seen here https://www.youtube.com/watch?v=y5XTQXrGFmo
Ii likee the idea on a basic level, and if we got clock chimes I’d be way more than satisfied.
Buuuuuuuut… you know I have to think of really unnecessary additions to things, so I propose a custom clock chime creator, either like Animal Crossing’s town tune, or via directly uploading a midi file that the clock reads like a music box
