They’re putting the cart before the horse.

That is, it’s been known for a long time that some people have brains wired to comprehend *abstracts*, such as mathematics or musical notation. Other people do not have this wiring, so after minimal learning they hit a dead end.

However, there are plenty of good “play by ear” musicians, who after years of trying *still* can’t read music.

So it is not the music that is improving their math grades, it is reading music and understanding it that way.

Anything that correlates with upper middle class parents works:

Kids whose parents can afford to buy $500 flutes when they're in high school.

Kids who ate lobster or caviar at least once a year while growing up...

Children who visited Disney World at least twice before they were 16...

Yep, look up guitarist Steve Morse, a virtuoso...can't read music.
