Maybe there is hope for me LOL
In a recent interview, Jiwoo talked about how when she was growing up she was scared to sing because she was tone deaf (couldn't hear the difference between notes)
Her fear got so great that she didnt even sing when she was completely alone because she thought someone might overhear. She continued training as a dancer, but her agency forced her to sing, thank god!
Apparently her voice coach had to be really tough on her to break her of her fear, and she would spend hours every day on her own trying to do the scales and hear the differerence between the notes.
Eventually, she learned it and was able to continue her studies in vocal training.
