Cho Kyu-Hyun (born February 3, 1988), best known mononymously as Kyuhyun, is a Korean pop singer. He is a member of the boy band Super Junior. He is also one of the first four Korean artists to appear on Chinese postage stamps. In China, Taiwan, and other Chinese speaking communities he is referred to as “Tsáo Guī Xián” (Chinese: 曺圭賢) which is based on the Chinese transliteration of the Hanja spelling.
Kyuhyun has a sister named Cho Ara. Kyuhyun’s father is in the education business and owns an academy. Largely due to his parents’ involvement with the education business, he spent a lot of time studying and preparing for exams.
Kyuhyun was initially urged to study law and had stated that if he did not become a singer, he would have chosen to become a lawyer. His original plans were abandoned once Kyuhyun joined a band in high school, where he became more interested in music and singing. His father was against his dream of singing but soon made a deal with Kyuhyun; if Kyuhyun did well on his college entrance exams and was accepted into a university, he would be allowed to pursue music.
Kyuhyun was accepted into Kyunghee University and his father allowed him to continue with his musical career. He graduated from Kyunghee University with a major in in Post Modern Music.
Cho Kyuhyun won third place at the Chin Chin Singing Competition in 2005. He soon signed under SM Entertainment and was featured in the video remake of TVXQ’s single “Hi Ya Ya”.
Prior to Kyuhyun’s addition to Super Junior, it was intended for the original twelve members to be separating and “graduating”, as the band was still presented as a project group at the time. The company then decided to drop the ’05 suffix following the growing popularity of the group.
Kyuhyun made his first appearance as a part of Super Junior in a news broadcast on May 23, 2006 when the group was introducing their new single, U. Kyuhyun made his debut performance on May 26, 2006 at SBS’s I-Concert performing the new single “U”, where it was also the group’s first return performance as a permanent group. Towards the end of 2006, Kyuhyun, along with Yesung and Ryeowook, was placed in Super Junior’s first subgroup, Super Junior-K.R.Y. The trio debuted on November 5, 2006 on KBS’s Music Bank.
It was revealed that Kyuhyun along with TRAX’s Jay, SHINee’s Jonghyun, and rookie singer Jino have formed a project group under their label.
SM The Ballad released their debut album, Miss You on November 29, 2010. They debuted on Inkigayo on November 28, 2010. In their debut album, Kyuhyun had his solo song, “Love Again”. Sumber : Wikipedia
