I've been doing this:
http://tonedear.com/ear-training/absolute-perfect-pitch-test
For some basic pitch testing. I set it to be as easy as possible, just two notes, C and D.
I get almost every question wrong, and I'm 50 iterations in.
Should I give up? Can I just not do it, is it a genetic limitation? Is there a way to change it and improve?
I really just don't know what I'm supposed to be hearing. They sound more or less the same to me, I can't pick out any identifying characteristic that yells "This is a C!" or "This is a D!"
