Soca music, or the "soul of calypso", is a genre of music that originated in Trinidad and Tobago in the 1970s. It is considered an offshoot of calypso, with influences from West African (e.g. kaiso) and East Indian rhythms.[1] It was created by Ras Shorty I (or Lord Shorty)[2][3][4] in an effort to revive traditional calypso, the popularity of which had been declining amongst younger generations in Trinidad due to the rise in popularity of reggae from Jamaica and soul and funk from the United States. From the 1980s onward, soca has developed into a range of new styles.
