Hi! Hello! This is an article that shows to you that REAL highest notes of SNSD/Girls Generation:
Sunny-G6 "Whistle Note"
Jessica-D6 "Chest note"
Yuri-C#6 "Falsetto note"
Taeyeon-C6 "Chest note"
Seohyun-Bb5 "Chest note"
Sooyoung-Bb5 "Falsetto note"
Hyoyeon-G#5 "Chest Note"
Tiffany-G5 "Chest note"
Yoona-D5 "Falsetto note"

I just saw this on YouTube,so please,check it out for more proofs and please take note,that I am just saying the truth! So no bashing please! :).

So,based on the facts above,our SunnyBunny hits the highest and the best high note!

But for me, A Singer does not refer on the high notes on how good he/she is,if she/he reaches high notes then good! Nice! But for me,A singer refers on how good her/his tesstitura and timbre is to show to the people how good she is.

So we're now done to our article,I hope you like It and enjoy! So thanks for reading this/my article! Thank you! :).
