The term "σκα" (pronounced "ska") refers to a music genre that originated in Jamaica in the late 1950s. It combines elements of Caribbean mento and calypso with American jazz and rhythm and blues. Characterized by its upbeat tempo and offbeat guitar or piano rhythms, ska music often features brass instruments, creating a lively and energetic sound. Ska music played a significant role in the development of other genres, including reggae and rocksteady. It gained popularity in the 1960s, particularly in the UK, where it influenced the 2 Tone movement, blending ska with punk rock elements. Today, ska continues to be celebrated worldwide, with various bands and festivals dedicated to the genre.
