The music from the Pacific coast, such as the currulao, is characterized by its strong use of drums (instruments such as the native marimba, the conunos, the bass drum, the side drum, and the cuatro guasas or tubular rattle). An important rhythm of the south region of the Pacific coast is the contradanza (it is used in dance shows due to the striking colours of the costumes). Marimba music, traditional chants and dances from the Colombia South Pacific region are on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.
