The Beguine is a dance, similar to a slow Rumba, that was very modestly popular in the 1930s, coming from the islands of Guadeloupe and Martinique, where the Martinique Beguine is a slow close dance with a roll of hips. If Cole Porter hadn't written (Don't let them) "Begin the Beguine," the dance would scarcely be remembered beyond the Caribbean. The song was introduced in Porter's "Jubilee" (1935), with a book by Moss Hart and added dialogue by Monty Woolley.
