How to evaluate the three tenors of South Korean female singer iu?

As a senior IU fan, let me talk about it

Tone: the bass is slightly hoarse and the treble is clear.

Singing skills: not particularly outstanding among Korean female singers, but delicate.

As for the three high notes, it is not a proof of singing, because she herself said that she only needed a little practice, but the high notes made IU famous.

Actually, many people don't think her bass is better.

Since the subject is asking about the difficulty of three high notes, it is not difficult, because it is easy to sing as long as the breath can top it. I am in the school choir. I'm almost that tall. Everyone can do it.
