Ska is a form of Jamaican music combining elements of traditional mento and calypso with an Americanjazz and rhythm and blues sound. It is notable for its shuffling, scratchlike tempo and jazz-like horn riffs on the offbeat.
Originating in Jamaica, possibly in the 1950s, it was a precursor to rocksteady and later reggae. It was the predominant form of music listened to by rude boys, although many ska artists condemned the violent subculture. It is also popular with mods and skinheads, with artists such as Symarip, Laurel Aitken, Desmond Dekker and The Pioneers aiming songs at these groups as early as the 1960s.
