Music of the Lesser Antilles: The music of the Lesser Antilles encompasses the music of this chain of small islands making up the eastern and southern portion of the West Indies.  Lesser Antillean music is part of the broader category of Caribbean music; much of the folk and popular music is also a part of the Afro-American musical complex, being a mixture of African, European and indigenous American elements.  The Lesser Antilles' musical cultures are largely based on the music of African slaves brought by European traders and colonizers.  The African musical elements are a hybrid of instruments and styles from numerous West African tribes, while the European slaveholders added their own musics into the mix, as did immigrants from India.  In many ways, the Lesser Antilles can be musically divided based on which nation colonized them.
