Choreography is the art of designing sequences of movements in which motion, form, or both are specified. Choreography may also refer to the design itself, which is sometimes expressed by means of dance notation. The word choreography literally means "dance-writing" from the Greek words "χορεία" (circular dance, see choreia) and "γραφή" (writing). A choreographer is one who creates choreographies.

The term choreography first appeared in the American English dictionary in the 1950s. Prior to this, movie credits used various terms to mean choreography, such as "ensembles staged by" and "dances staged by".

Choreography is used in (but not limited to) the fields of cheerleading, cinematography, dance, gymnastics, fashion shows, ice skating, marching band, show choir, theatre, and synchronized swimming.

In dance, choreography is also known as dance composition. Dance compositions are created by applying one or both of these fundamental choreographic techniques:

Choreographic techniques are: mirroring (facing each other and doing the same), retrograde (performing a sequence of moves in reverse order), canon (people performing the same move one after the other), levels (people higher and lower in a dance), shadowing (standing one behind the other and performing the same moves), unison (two or more people doing a range of moves at the same time).

Justin Drew Bieber ( /ˈbiːbər/ BEE-bər, born March 1, 1994) is a Canadian Pop/R&B singer-songwriter, musician, and actor. Bieber was discovered in 2008 by Scooter Braun, who came across Bieber's videos on YouTube and later became his manager.

Reid. Bieber's debut single, "One Time", was released in 2009 and peaked in the top twenty in Canada and charted in the top thirty in several international markets. His debut album, the seven-track EP My World, followed in November 2009, and was soon certified platinum in the United States. He became the first artist to have seven songs from a debut album chart on the Billboard Hot 100.

Melissa Arnette "Missy" Elliott (born July 1, 1971) is an American rapper, singer-songwriter, record producer, dancer and actress. A five-time Grammy Award winner, Elliott, with record sales of over seven million in the United States, is the only female rapper to have six albums certified platinum by the RIAA, including one double platinum for her 2002 album Under Construction. Elliott is known for a series of hits and diverse music videos, including "The Rain (Supa Dupa Fly)", "Hot Boyz", "Get Ur Freak On", "One Minute Man", "4 My People", "Work It", "Pass That Dutch", and "Lose Control". In addition, she has worked extensively as a songwriter and producer for other artists, both alone and with her fellow producer and childhood friend Timbaland, with whom she received her first production credit on R&B singer Ginuwine's 1996's album Ginuwine...the Bachelor.

Elliott was born on July 1, 1971, in Portsmouth, Virginia. She is the only child of mother Patricia, a power-company coordinator, and father Ronnie, a Marine. At the age of four in 1975, she wanted to be a performer, though she knew no one took her seriously, as she was always the class clown. While her father was a Marine, the family lived in Jacksonville, North Carolina, in a mobile home. Elliott enjoyed school for the friendships she formed and had little interest in school work, though an IQ test classified her above average and she was able to jump two years ahead of her class. This made her feel increasingly isolated, so she purposely failed all her classes, eventually returning to her age-appropriate class. When her father returned from the Marines, they moved back to Virginia, where they lived in a vermin-infested shack.
