While Lesser Antillean music is very often discussed as a music area, this division is of limited usefulness. The islands of the Lesser Antilles divide musically along linguistic lines, with the most significant overlap coming from Dominica and Saint Lucia, both primarily Anglophone but strongly influenced by a French colonial past. Because the islands are divided linguistically, the term "Antillean music" is usually used in reference to one such music area. Thus, for example, the "Rough Guide to World Music" features a chapter on "Antillean music", which is entirely about the French Antillean islands of Martinique and Guadeloupe, with a brief sidebar specifically about the Dutch Antilles.
