The former British colonies include Trinidad and Tobago, whose calypso style is an especially potent part of the music of the other former British colonies, which also share traditions like the Big Drum dance. The French islands of Martinique and Guadeloupe share the popular "zouk" style and have also had extensive musical contact with the music of Haiti, itself once a French colony though not part of the Lesser Antilles. The Dutch colonies of Curaçao, Bonaire and Aruba share the combined rhythm popular style. The islands also share a passion for kaseko, a genre of Surinamese music; Suriname and its neighbors Guyana and French Guiana share folk and popular styles that are connected enough to the Antilles and other Caribbean islands that both countries are studied in the broader context of Antillean or Caribbean music.
