4Minute
Cube Entertainment announced Ga Yoon as a member of the girl group 4Minute under Cube Entertainment in May 2009 together with Jeon Ji-yoon, Kwon So-hyun, Kim Hyun-a and Nam Ji-hyun. Cube Entertainment released a teaser for their first single "Hot Issue" on June 10 while the single debuted on June 18. The group promoted the song from its release until mid-August. At the end of August, 4Minute released a mini-album called "For Muzik" alongside their second single "Muzik". 4Minute won a mutizen award and a Mnet award for their second single "Muzik". Their third single "What A Girl Wants" was released shortly after the release of their EP.

After a successful promotion period, the group released a new mini-album entitled HuH (Hit Your Heart) for their comeback on May 19, 2010. And after almost a year of hiatus, the group then released their first full length Korean album titled 4MINUTES LEFT. The album and their two lead promotional singles maintained their positions in the top 10 of many Korean REAL TIME Charts.

After the promotion of their first full length album, the group focused on their Japanese activities. After more than a year of hiatus, the group made a highly anticipated comeback last April 9 with their third mini album ‘Volume Up’, which topped music charts. 4Minute achieved #1 status three times on music shows; two times on Show Champion and one time on M!
