ABSTRACT
Almost all of the countries of Africa, Asia, Oceania and Latin America are non-industrial societies. In these lands, as in certain strata of western countries, music for the majority of the population - which consists of workers - is closely interwoven with everyday work and life: it is not merely an entertainment, a source of satisfaction or an art cultivated for its own sake. Music, for the professional musician or the cultivated amateur on the other hand, must have more artistic depth. It is the subject of theorization and it is made to conform to certain cosmogonic or philosophical ideas. It then becomes a principal source of entertainment or an essential adjunct of ceremonies.
