Yoruba music is the pattern/style of music practiced by the Yoruba people of Nigeria, Togo, and Benin. It is perhaps best known for its extremely advanced drumming tradition and techniques, especially using the gongon hourglass shape tension drums. Yoruba folk music became perhaps the most prominent kind of West African music in Afro-Latin and Caribbean musical styles; it left an especially important influence on the music used in Santería practice and the music of Cuba. The Yoruba people of south-western Nigeria are also one of the most socially diverse groups on the African continent. A major feature that sets them apart from other groups in Nigeria is their accomplishment in the arts and entertainment industry, especially in music. Jùjú, fùjì, àpàlà and sákárà music are among the popular genres of music that originated among the Yoruba people. How and when these forms of music emerged in the Nigerian music scene has remained a puzzle to historians. However, it is generally believed that these genres of music originated from popular folk music among the Yoruba people during the colonial era and gradually grew to become popular forms of music in the country after independence in 1960. This paper traces the origin and the significance of Yoruba traditional music in Nigeria as well as its roles in popularising the cultural values and heritage of the Yoruba people at home and in the diaspora. It is argued that music constitutes an important medium through which Yoruba values have been sustained in society in the face of the aggressive cultural imperialism that is fast encroaching the African continent. For a comprehensive discussion of Yoruba music, see Bode Omojola's book, Yoruba Music in the Twentieth Century (University of Rochester Press, 2012). Folk music Ensembles using the dundun play a type of music that is also called dundun. These ensembles consist of various sizes of tension drums along with special band drums (ogido). The gangan is another such. The leader of a dundun ensemble is the oniyalu who uses the drum to "talk" by imitating the tonality of Yoruba. Much of Yoruba music is spiritual in nature, and this form is often devoted to Orisas. Rhythmic structure The most commonly used key pattern, or guide pattern in traditional Yoruba drumming is the seven-stroke figure known in ethnomusicology as the standard pattern. The standard pattern is expressed in both a triple-pulse (12/8 or 6/8) and a duple-pulse
