Freestyle is an improvisational form of rapping, performed with few or no previously composed lyrics, which is said to reflect a direct mapping of the mental state and performing situation of the artist. It is non-scripted, non-rehearsed, uncut, and the rawest form of hip-hop. Artists will often refer to places and objects in their immediate setting. Freestyle rapping forces an individual to think on the spot, describe their surroundings, and, to a certain degree, rap uncensored from what is inside. It is similar in this sense to improvisational music or acting and draws comparisons to improvisational Jazz in particular.
Freestyle made its Olympic debut as a demonstration sport in Calgary in 1988. With the acceptance of Moguls as an official medal sport in 1992, and with the subsequent acceptance of Aerials in 1994, Freestyle has gained even more widespread attention and undergone phenomenal growth.
