Calypso is a style of Afro-Caribbeanmusic which originated in the British and French colonial islands of the Caribbean at about the start of the 20th century. It is an especially integral part of Trinidadian music. The roots of the genre lay in the arrival of African slaves, who, not being allowed to speak with each other, communicated through song. This forged a sense of community among the Africans, who saw their colonial masters change rapidly, bringing French, Spanish and British music styles to the island of Trinidad. The French brought Carnival to Trinidad, and calypso competitions at Carnival grew in popularity, especially after the abolition of slavery in 1834. While most authorities stress the African roots of calypso, in his 1986 book Calypso from France to Trinidad, 800 Years of History veteran calypsonian The Roaring Lion (Rafael de Leon) asserted that calypso descends from the music of the medieval French troubadours.
Over 100 years ago, calypso further evolved into a way of spreading news around Trinidad. Politicians, journalists, and public figures often debated the content of each song, and many islanders considered these songs the most reliable news source. Calypsonians pushed the boundaries of free speech as their lyrics spread news of any topic relevant to island life, including speaking out against political corruption. Eventually British rule enforced censorship and police began to scan these songs for damaging content. Even with this censorship, calypsos continued to push boundaries.
