no i don't go deaf. I learned to figure out songs by ear a while ago, and it has been going on pretty good, I was able to learn three songs in a week, and then I took a break for two days, and when I tried to learn another song, it feels like I cannot figure it out. It was like I'm new to this thing is it just because I'm not in the mood or what?
What song did you try to learn? What songs have you learned before? Some songs are harder to figure out by ear than others. I learn mostly by ear and I run into songs that give me a lot of trouble all the time.
Sometimes that can happen when you consistently practice/train on something, even if the break was a small one. However, if you keep trying to train your ear after the "loss of ability", your foundation should become stronger as a result.
