> Which is a strange way to teach a system that essentially comes out of physics and arithmetic. There are twelve notes for a reason.
There is of course a lot of physics involved. But there is at least as much convention at play. So imho this is a very one sided way of looking at it.
There is a physical reason the 12 notes are those 12 notes (though the exact frequencies assigned are influenced by culture as well), but lots of different cultures use less notes, or more, or extra notes inbetween.
So 'Because that is the convention.' is imho at least a good an explanation as the physics one.
