Talking drum in the context of "Omele ako"

The drum is a member of the percussion group of musical instruments. In the Hornbostel–Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a percussion mallet, to produce sound. There is usually a resonant head on the underside of the drum. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Drums may be played individually, with the player using a single drum, and some drums such as the djembe are almost always played in this way. Others are normally played in a set of two or more, all played by one player, such as bongo drums and timpani. A number of different drums together with cymbals form the basic modern drum kit. Many drums are played together with other instruments.

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).

Hourglass drums are a sub-category of membranophone, or drum, characterized by an hourglass shape. They are also known as waisted drums. Drumheads are attached by laces, which may be squeezed during a performance to alter the pitch.The category also includes pellet drums such as the damaru, although not all pellet drums are hourglass shaped (such as the Korean do, nodo, noedo, and yeongdo, which are barrel shaped).

Hourglass drums exists in most regions of the world, but have very different construction methods, dimensions, purposes and playing methods. The label of hourglass drum is hence as generic as the label for bowed instrument or reed instrument. Thus the designation of Hourglass drum is used as a category in general instrument construction and does not refer to any particular uniform instrument.
