Signature

Moon Byul-yi (Hangul: 문별이), born on December 22, 1992, is a South Korean rapper and songwriter. She is known professionally as Moonbyul (Hangul: 문별). She is a member of the popular K-pop girl group Mamamoo and its special group Mamamoo+.

Moonbyul started her solo music career in May 2018 with a digital song called "Selfish." She has helped write over 100 songs, showing her talent as a songwriter.

Early Life and Education

Moon Byul-yi was born in Bucheon, South Korea, on December 22, 1992. When she was in middle school, she became very interested in singing. This happened after she saw the group TVXQ perform their song "Rising Sun." She decided to become a singer after getting good feedback from a school performance.

She also looked up to Girls' Generation and their leader Taeyeon. Moonbyul even went to SM Entertainment's academy to follow her dreams. She finished high school at Wonmi High School. Later, she studied media music and vocals at the Paekche Institute of the Arts.

Her Name and Its Meaning

Moonbyul's stage name combines her family name "Moon" with her given name "Byul-yi." Her given name "Byul-yi" means star in Korean. Moonbyul has shared that her father chose the name "Byul-yi" because he was inspired by the night she was born.

She also uses the nickname "Moonstar" when she raps. This name directly translates the meaning of her Korean name into English. Since she started her career, Moonbyul has used "Moonstar" in many of her song lyrics. The moon and stars are often linked to her as well.

Her Music Career

Starting with Mamamoo

Moonbyul joined her music company, RBW, in 2011. She first passed her audition as a singer and trained to be one. However, her producer suggested she become a rapper instead. The group needed a rapper, and Moonbyul agreed to switch. Even though she was new to rapping, she debuted with Mamamoo on June 19, 2014.

She became the main rapper and performer for Mamamoo. The group debuted with their song "Mr. Ambiguous." Mamamoo quickly became known for their strong singing style. Moonbyul also helped create the dance moves for their first song. She was good at freestyle and hip-hop dancing. She would even make up her own dance routines for monthly evaluations.

In November 2016, Mamamoo performed at the Blue Dragon Film Awards. This is a very important film awards show in South Korea. They performed their song "Decalcomanie" with a fun twist. They added lines from famous movies. Moonbyul's line, "Jung Woo-sung, if I drink this in one shot, will you go out with me?", became very popular. This moment went viral and helped their song become a big hit.

In June 2017, Moonbyul released her first solo song, "Love & Hate." This song was part of Mamamoo's fifth mini-album, Purple. She wrote the song about a past relationship. It talks about feeling lonely even when someone is there.
