World music is an English phrase for styles of music from non-Western countries, including quasi-traditional, intercultural, and traditional music. 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". This music that does not follow "North American or British pop and folk traditions" was given the term "world music" by music industries in Europe and North America. The term was popularized in the 1980s as a marketing category for non-Western traditional music. It has grown to include subgenres such as ethnic fusion (Clannad, Ry Cooder, Enya, etc.) and worldbeat. Lexicology The term "world music" 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 doctoral programs in the discipline. To enhance the learning process (John Hill), 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 term virtually meaningless. Forms Examples of popular forms of world music include the various forms of non-European classical music (e.g. Chinese guzheng music, Indian raga music, Tibetan chants), Eastern European folk music (e.g. the village music of the Balkans, The Mystery of the Bulgarian Voices), Nordic folk music, Latin music, Indonesian music, and the many forms of folk and tribal music of the Middle East, Africa, Asia, Oceania, Central and South America. The broad category of world music includes isolated forms of ethnic music from diverse geographical regions. These dissimilar strains of ethnic music are commonly categorized together by virtue of their indigenous roots. Over the 20th century, the invention of sound recording, low-cost international air travel, and common access to global communication among artists and the general public have given rise to a related phenomenon called "crossover" music. Musicians from diverse cultures and locations could readily access recorded music from around the world, see and hear visiting musicians from other cultures and visit other countries to play their own music, creating a melting pot
