taeyeon can hit the best high note

I believe since Sica has a higher voice than Taeyeon, she hits the high notes better... Esp. From what I see in songs she looks like it comes with easy and Taeyeon seems the same but I prefer Jessica's high notes rather than Taeyeon's ^-^

@yangchentsomo16,Sunny hits the best and highest note and it is "G6",Jessica's highest note is D6,Taeyeon's highest note is C6,Seohyun and Sooyoung is Bb5,Yuri's highest note is C#6,Hyoyeon's highest note G#5,Tiffany's highest note is G5 while Yoona's highest note is D5,this is True!,check it out on YouTube for their Individual vocal ranges,please,take note, I am just saying the truth! :).

Also,I agree with BlackPearlLuver,I think Taeyeon has a louder voice than Sica but Sica has a higher voice Taeyeon.

Also,do you watched,a video,than Seohyun sings high note of twinkle "nune hwak twijahna!!!!!!!!",Tiffany tries to reach It but she can't,I am not hating but I am just saying what's the truth! :).

From what I see it's Jessica. It's just asking who is better, no need to compare so much...

@Tippany if you are talking bout me.... Sorry! Didn't mean to compare or get anyone mad :)

Obviously it's Jessica and agree with Cha_Mae! :).

@BlackPearlLuver
You can think as you like, but no I wasn't referring it to anyone and I'm not mad and beside your comment really didn't make any comparison. It's just that every time there are polls about something there always comparison toward this and that.

taengsic but i perfer sica's

or Taeyeon

Her voice in C5 is just AMAZING.

Jessica can hit a high note and a high pitched note

Jessicas High Notes they are high but flat with no tune :/
