Soca, or soul calypso, is a dance music that originated in Trinidad from calypso. It combines the melodic lilting sound of calypso (based on the original Steel Pan) with insistent (usually electronic) percussion. Soca music has evolved in the last 20 years primarily by musicians from Trinidad, Barbados, and the Lesser Antilles.

The reputed father of soca was Lord Shorty (né Garfield Blackman), whose 1963 recording of "Cloak and Dagger" started the trend. It would be Lord Kitchener who would begin the noticeable and accredited transition and Byron Lee & the Dragonaires, which made soca a West Indian social wave, but the Baha men, Kevin Lyttle, and others in the 21st century brought it to American recognition.

Like calypso, soca was used for both social commentary and risqué humor, though the initial wave of soca acts eschewed the former. Lord Shorty was disillusioned with the genre by the 1980s because soca was being used to express courtships and sexual interests. Like all things related to sexual freedom, it became embraced because of its ability to reflect what people were thinking and their desires in a society that was sexually repressed. Soca music became an expression of sexuality through metaphors in the West Indies. Soon after, Shorty moved to thePiparo forest, converted to the Rastafari movement and changed his name to Ras Shorty I. There, he created a fusion of Reggae and gospel music called jamoo in the late 1980s.

Some of the greatest soca artists of all time are Shadow, Mighty Sparrow, Krosfyah, Byron Lee & the Dragonaires, and more recently artists such as Alison Hinds, Atlantik, Machel Montano, Destra Garcia, Shurwayne Winchester, Denise Belfon, and Maximus Dan.

Some soca songs that have become hits:

• "Hot Hot Hot" - Buster Poindexter (originally recorded by Arrow)
• "Follow the leader" - Soca Boys (originally recorded by Nigel and Marvin Lewis), a more recent version by S.B.S.
• "Who Let the Dogs Out" - Baha Men (originally recorded by Anslem Douglas)
• "Sweet Soca Music" - Sugar Daddy
• "Turn Me On" - Kevin Lyttle
• "Tempted to Touch" - Rupee
• "We Not Givin' Up" - Machel Montano and Xtatik

Soca music has evolved like all other music over the years, with Calypsonians experimenting with other rhythms, some examples are the following:

• Rapso : trinidad dialect hip-hop with smooth calypso melody and bold lyric
• Chutney-soca: A fusion of traditional Indian percussion and style of singing and Calypso; Tempo usually around 154 BPM
• Ragga Soca: A fusion of Jamaican Dancehall and Trinidad's Soca and the original soca, which is an uptempo calypso beat with moderate bass and electronic instruments.

Soca has also been experimented with in Bollywood films, Bhangra, and new Punjabi pop.

The nickname of the Trinidad and Tobago national football team, the Soca Warriors, refers to this musical genre.
