World music is a musical category encompassing many different styles of music from around the world, including traditional music, neotraditional music, and music where more than one cultural tradition intermingle. World music's inclusive nature and elasticity as a musical category pose obstacles to a universal definition, but its ethic of interest in the culturally exotic is encapsulated in Roots magazine's description of the genre as "local music from out there". The term was popularized in the 1980s as a marketing category for non-Western traditional music. Globalization has facilitated the expansion of world music's audiences and scope. It has grown to include hybrid subgenres such as world fusion, global fusion, ethnic fusion and worldbeat.TerminologyThe term has been credited to ethnomusicologist Robert E. Brown, who coined it in the early 1960s at Wesleyan University in Connecticut, where he developed undergraduate through the doctoral programs in the discipline. To enhance the process of learning, he invited more than a dozen visiting performers from Africa and Asia and began a world music concert series. The term became current in the 1980s as a marketing/classificatory device in the media and the music industry. There are several conflicting definitions for world music. One is that it consists of "all the music in the world", though such a broad definition renders the word virtually meaningless. The term also is taken as a classification of music that combines Western popular music styles with one of many genres of non-Western music that are also described as folk music or ethnic music. However, world music is not exclusively traditional folk music. It may include cutting edge pop music styles as well. Succinctly, it can be described as "local music from out there", or "someone else's local music". It is a very nebulous term with an increasing number of genres that fall under the umbrella of world music to capture musical trends of combined ethnic style and texture, including Western elements (examples noted in this section).
