When I was little, I wanted to make a song out of the sound of squeaking gates and doors. They’d have to be native gates: playing their own notes… but it would only take a few doors/gates squeaking because they have a large range of notes with each of them, depending how you play the door.
[actually I’ve played doors/gates a lot in my life]
The floppy disk drive and dot matrix printer stepper motor songs are like that. Definitely my kind of thing.
