The smaller islands of Saint Martin, Saba and Sint Eustatius largely share in the same folk instruments, dances and songs as their neighbors; however, these islands remain largely unstudied. Saba is home to a vital percussive music tradition, most closely associated with private parties, using instrumentation similar to Curaçao, Bonaire and Aruba. Saint Martin is home to a national dance form called the "ponum", which dates to the 19th century and was only displaced by string bands in the mid-20th century. Saint Martin is also home to a calypso-like "quimbe" song form, that remains a major part of the island's culture.
