T-ara (/tiˈɑːrə/; Korean: 티아라) is a South Korean girl group formed in 2009 by MBK Entertainment (formerly known as Core Contents Media). Their most well-known lineup featured Boram, Qri, Soyeon, Eunjung, Hyomin and Jiyeon. T-ara's career is marked by hook-heavy dance-pop music, a result of their close partnership with composer Shinsadong Tiger. A broad array of visual concepts have earned the group a "chameleon-like" reputation. The group officially debuted in July 2009 with the single "Lie", following line-up changes due to creative differences. Their debut studio album Absolute First Album was released in December 2009 and spawned several hit songs including "TTL (Time to Love)", "Bo Peep Bo Peep", and "You Drive Me Crazy".

T-ara gained nationwide recognition after releasing "Roly-Poly" in 2011, which went on to become the Gaon chart's best-selling single of the year. At the height of K-pop's popularity in Japan, T-ara signed onto management agency J-Rock for $4.7 million—reportedly the highest figure of any Korean girl group expanding into the territory at the time. Both their debut Japanese single and studio album reached number one on the Oricon weekly charts and were subsequently certified Gold. T-ara's late-2011 Korean release Black Eyes spawned three consecutive number ones: "Cry Cry", "We Were in Love" and "Lovey-Dovey". In 2012, T-ara experienced a dip in popularity as the group faced accusations of internal discord, resulting in Hwayoung's immediate departure with Areum following a year after. T-ara's later material was released to varying degrees of success before the group began focusing on promotional activities in China, where they attracted attention for their cover of Chopstick Brothers' "Little Apple" in 2014. T-ara is regarded as one of the most popular K-pop girl groups in China.

T-ara's final release as six members was tentatively scheduled for May 2017, ahead of Soyeon and Boram's expiring contracts; however, conflicts with their management delayed What's My Name? until June 2017, effectively without their involvement. Qri, Eunjung, Hyomin and Jiyeon had previously extended their terms with MBK Entertainment until December 2017.

2009–2010: Formation and debut

The original pre-debut five T-ara members (Jiae, Jiwon, Eunjung, Hyomin and Jiyeon) trained together for three years under Mnet Media. The meaning behind the group's name, which is based on the word "tiara", comes from the idea that they will become the "queens of the music industry". In April 2009, they released their first song "Joheun Saram (Ver. 1)" (좋은 사람, "Good Person") for the Cinderella Man soundtrack. Jiyeon teamed up with labelmates SeeYa and Davichi for a collaboration single titled "Yeoseong Shidae" (여성시대, "Women's Generation"), which was released in May 2009. In June 2009, Mnet Media announced that Jiae and Jiwon would be leaving T-ara due to differences in music style. The first new member to be added to the group was Boram, the daughter of singer Jeon Young-rok and actress Lee Mi-young. Soyeon, a former trainee of S.M. Entertainment who was supposed to be the leader of Girls' Generation,[14] and Qri were added to T-ara three weeks prior to debut. In early July 2009, the group was moved from Mnet Media to its subsidiary company Core Contents Media.

T-ara made their debut on MBC's Radio Star talk show on July 29, 2009. Their first performance was on Mnet's M Countdown music show on July 30, where they performed "Geojitmal" (거짓말, "Lies") and "Norabollae?" (놀아볼래?, "Wanna Play?") from their debut single. Their debut was looked upon negatively by webpostings, where people stated that it was lipsynched and commented that it seemed like an "elementary school" performance. The group announced afterwards that future performances would be live. In September 2009, Eunjung, Soyeon, Hyomin and Jiyeon collaborated with labelmates Kwangsu, Jihyuk, and Geonil of Supernova for the single "TTL (Time to Love)". It was released on September 15, 2009, and became both groups' first number one song as it topped many of the online charts. T-ara and Supernova collaborated again for "TTL Listen 2", a sequel to "TTL (Time to Love)", which was released on October 9, 2009, and included all the members from both groups.

T-ara released their debut studio album, Absolute First Album, on November 27, 2009. In order to determine the album's title track, Core Contents Media held a survey in which the public had to choose between "Bo Peep Bo Peep" or "Cheoeum Cheoreom" (처음처럼, "Like the First Time"). 9,000 people took the survey on various music portals with 53% (4,770 people) choosing "Cheoeum Cheoreom" over "Bo Peep Bo Peep". However, the latter was promoted on music shows instead for unknown reasons. "Bo Peep Bo Peep" peaked at number four on the Gaon chart, while "Cheoeum Cheoreom" peaked at number ten.[ They held their comeback performance on Music Bank on December 4, 2009. At the 24th Golden Disk Awards, T-ara was awarded Rookie of the Year along with girl group 4minute.

The group won their first-ever music show award with "Bo Peep Bo Peep" on the New Year's Day episode of Music Bank.[25] The song went on to win five awards in total: two on Music Bank and three on Inkigayo, earning them a "Triple Crown". Later in January 2010, the group announced promotions for their follow up single, "Cheoeum Cheoreom", which ended quickly as Soyeon was diagnosed with H1N1. The same month, T-ara made a cameo appearance on the seventh and eight episodes of God of Study, in which Jiyeon played a main role.

In February 2010, the group announced a re-release of their debut album under the title Breaking Heart. The two lead singles, "Neo Ttaemune Michyeo" (너 때문에 미쳐; "I Go Crazy Because of You") and "Naega Neomu Apa" (내가 너무 아파, "I'm Really Hurt"), were digitally released on February 23, 2010, and peaked at number one and number thirty-one on the Gaon chart, respectively. T-ara held their comeback performance on the same day on M Countdown, and won several music awards for "Neo Ttaemune Michyeo" over the course of their promotions: two consecutive Mutizen wins on Inkigayo and one first place award on M Countdown. Breaking Heart was released physically on March 3, 2010, peaking at number two on the weekly Gaon chart and number thirty-five on the yearly chart; selling 40,695 copies. After promotions for "Neo Ttaemune Michyeo" ended, T-ara performed "Naega Neomu Apa" on music shows until early April 2010. In June 2010, the group donated all the proceeds of the World Cup merchandise sold on their online clothing shop T-ara Dot Com to a charity for African children. On July 16, 2010 T-ARA representatives announced the addition of Hwayoung Ryu as the seventh member of the group. The reason given was that with so many solo projects, they would be able to have a more complete lineup for T-ARA when individual members were filming or doing other appearances. They also stated that it would allow the members to undertake more solo activities, and would give them all some relief from their heavy schedules.

In November 2010, The group starred in the third season of the reality show Hello Baby, in which they took care of Moon Mason and his two brothers. T-ara released the digital download for "Wae Ireoni" (왜 이러니, "Why Are You Being Like This"), the lead single for their first extended play, Temptastic, on November 23, 2010.

The album's physical release was delayed until December 3 due to the bombardment of Yeonpyeong earlier in November 2010. T-ara held their first comeback performance through Music Bank on December 3 and began promotions with their new seventh member, Hwayoung, and new leader, Boram, and received two consecutive wins for "Wae Ireoni" and "Yayaya" on M Countdown.
