There's virtually no cognitive load if you already know music theory. That's a very important distinction - music theory in its current state is completely undiscoverable for no good reason. How undiscoverable? I grew up in a fairly music-oriented family and played a lot of instruments as a kid, but didn't formally study music theory. It wasn't until I read parent that I realized "fifth", "third", etc. are 1-indexed ordinals, and not some inscrutable scheme involving fractions. Everything suddenly makes way more sense. I feel fairly confident that sane terminology would greatly ease this problem.
