Hello Willowham.
Interesting little story, it kind of borders on prosetry. Here are some of my thoughts on world and wordsmithing.
If, as you say this is a world of sound and music, how does the character know what red is? are they a traveller here, or do they perchance navigate by echolocation?
I loved a chunk of your word choice, the 'dull listless red' of the alarms makes it feel very poignant. The only one I shy away form is 'literally silent'. the literally sort of breaks narrative, as it sound like it's addressed to us. I also liked the second person POV, there isn't all that much good second person writing out there.
In short, think about how your character would know the world, and expand it a little, I want to know more.
In other news, I am upgrading my computer's Syncthing to Beryllium Bedbug. You will have to follow suit if you want to sync from me. (The update is worth it, as it's possible now for files to be relayed around firewalls. With a bit of testing, maybe we can get DarkRawen back.)
Aeirdrome, your new icon keeps surprising me.
