In Spain, the term rumba was introduced in the early 20th century as rumba flamenca, one of the palos (styles) of flamenco. Particularly, it is considered one of the cantes de ida y vuelta, since flamenco itself might have had an influence on Cuban rumba, particularly on its vocal style. However, musicologists agree that rumba flamenca does not truly derive from Cuban rumba, but from guaracha, a fast-paced music style from Havana.
