Yeah, I was wondering if it was context sensitive, by for example, country? As I'm in England. Different terms for different countries or something? I'm not really sure.
But it is stupid, it came up when we were analysing this piece and saw that the tonal centre was pretty much the aeolian mode, so I said as a passing comment whilst he explained some mode stuff that the aeolian will be the same as the A Natural Minor, and he just said he's never heard of it before, and that he's only ever come across Harmonic and Melodic minor scales, which, to be honest, I was slightly suprised by.
I've shown him an explanation of a natural minor scale from my published music theory book, but he still won't completely accept it. It's pretty annoying.
