Major Disaster

Discussing intervals with a 10-yr-old.  We'd talked 'perfect'.  Now for major and minor.

Me: So, if we forget this is music, what's major?  Like, a major ... disaster [the recent events of our country at the forefront of my mind].
Girl [quite seriously]: Bad.  Really bad.
Me: What if it was... um... they're all negative examples in my head... Okay.  What about a minor problem?  What would that be?
Girl: Not good.  But small.
Me [relieved]: Yes.  Minor is small, major is big.

Thirds

A grade 9 girl, learning a new piece.  In 4th position, her fingers were not quite sure of their spacing.

Me: What's that interval? [C-E]
Girl: 3.
Me: Ahem.
Girl: A third.
Me: Better.  What sort of a third?
Girl: Minor.
Me: Um, why?
Girl: Because it sounds really creepy.
Me: Ooh.  [I played it an octave lower]  How about then?
Girl, very confused: Major.  Definitely.  Not creepy at all.

[In case you're not sure - C to E is a major third]
