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).

Michael Willesee (born 29 June 1942) is an Australian television presenter.

Mike Willesee came to prominence in 1967 as a reporter for the ABC's new nightly current affairs program This Day Tonight (TDT), where his aggressive style quickly earned him a reputation as a fearless political interviewer.

Willesee figured prominently in the controversy that erupted over the decision in early 1967 by the Liberal government, led by Prime Minister Harold Holt, not to reappoint the ABC Chairman Dr James Darling. This decision was rumoured to have been the result of the government's anger over critical coverage of its policies on the ABC. Willesee's own critical comments about the decision on TDT on 2 April further angered Holt, who questioned the ABC's impartiality and implied that Willesee (whose father Don Willesee was a Labor Senator; in 1972 he would become Foreign Minister in Gough Whitlam's Labor government) was politically biased. Holt's remarks backfired, as they provoked strong protests from both Willesee and the Australian Journalist's Association.
