"Kwadril" music is provided by an ensemble consisting of a four-stringed instrument, the cuatro (instrument), a rattle, the "chakchak", bones called "zo", a violin, banjo ("skroud", "bwa pòyé"), mandolin and guitar. A kwadril consists of five separate dances: the "pwémyé fidji", "dézyèm fidji", "twazyèm fidji", "katwiyèm fidji" (also "avantwa" or "lanmen dwèt") and "gwan won" (also "grande rond"). The musicians may also use a "lakonmèt" (mazurka), schottische or polka; the "lakonmèt", also called the "mazouk", is especially popular and is the only closed couple dance which originated in Saint Lucia.
