I updated the Ear Trainer with a new exercise and interval associations.
Looking at my server logs, I can see that very few people have tried the ear training tool. I really hope this is because my visitors already have great relative (or absolute) pitch, or they already have some other method they use.
I fear, though, that it's because many players don't feel the need to develop their ears. It just never enters their mind. I'm not trying to be critical of anyone. After all, I didn't know anything about ear training until my freshman year of college (and I was a music major!). But, when I did learn about ear training, and when I realized it was the key to understanding and creating music, I was really upset that I hadn't been doing it all along.
