I was pleased to read recently that my old elementary school has a new vocal music classroom. I'm decades removed from being a grade school student, and I have no kids in school, but I think that any subject that's important enough to teach deserves its own classroom. A spacious room in which classes can sing and learn music theory should be more inspiring to students and teachers than a supply cart that a music teacher transports from room to room.
The treble clef on the new classroom floor shows that the room is a dedicated space for music-making--and that's the right message to convey.
