Nine Muses (Korean: 나인뮤지스, often stylized as 9Muses) was a South Korean girl group formed by Star Empire Entertainment in 2010 with an admissions and graduation concept. The group’s final lineup consisted of four members: Gyeongree, Hyemi, Sojin, and Keumjo.
The formation of Nine Muses was announced on March 26, 2010. Their first single album Let’s Have a Party on August 12, 2010. The lead single, “No Playboy”, was produced by composers Rainstone and Park Jin-young. In October, Jaekyung withdrew from Nine Muses to focus on her modeling career and was replaced by Hyuna. To advance into the Japanese market, on December 26, 2010, the group performed six songs on Seoul Train, an event in which K-pop artists and groups perform for their Japanese fans, alongside V.O.S. and ZE:A.
In January 2011, it was announced that members Bini, Rana, and Euaerin would leave Nine Muses to pursue other areas, and that they will not receive replacements. However, three months later Euaerin re-joined the group. The group returned as a 7 member group with the release of their digital single “Figaro” and its music video on August 18, 2011. During the single’s promotional period, Star Empire Entertainment announced that the group name would be changed to Sweet Candy, as it would confuse people if Nine Muses was a group with only 7 members. A month later, the company confirmed that the group name was not changing, because they would add two new members to the group in the future, once again making the group a nine member group.
