Music is an integral part of Igbo culture, it is exceptional and incorporated into all of aspects of Igbo life ranging from the religious usage, through the dance music, down to the women who sing to get their rivals flared up. Ndi Igbo have several styles and forms of rendering music, and here, I am going to mention about six of the most prominent styles:
1. UBO
Ubo is an enchanting combination of various musical instruments coming off wonderfully in a harmony of words and sounds. Basically, Ubo is performed with Igba, Udu, Ichaka, Ekwe, among others. It is good to point out that while me may call this type of music, Ubo, there is also a special kind of Igbo musical instrument called Ubo, which in English, can be referred to as thumb piano. But this Ubo -- thumb piano, is not used in this style of music performance. Gradually, Ubo is collapsing into the regular Igbo highlife music with several foreign instruments being introduced. Ubo, as it were, is predominantly seen in the northern parts of Igboland (Enugu and Anambra states). Notable among Ubo makers are Pammy Udubonch, and here is a clip to showcase what Ubo is at the moment.
2. EKPILI
Ekpili is a long-standing kind of Igbo music, it dates back to a period that no one can actually pinpoint. However, Akunwafor Obiligbo is noted as the pioneer in this category of music making. There is a contention as to what could really be termed Egwu Ekpili, for some, it is the use of a thumb-paino known as Ubo aka, for others it is the use of Ichaka or Oyoko -- a vessel laced with beads that produces a rattling sound. And yet for many others, it is a combination of both. Egwu Ekpili captures stories, narrates them to the tune of thumb piano/rattles, and ultimately delivers an unusual kind of harmony.
3. OGENE
Sometimes, many people tend to take Ubo for Ogene, and vice versa. However, the major difference is that Ogene is Ogene – the metal gong. It is rarely accompanied by drums. Ogene players simply use different Ogenes to produce different sounds, with the Oja--flute blaring in synchrony. Ogene has survived over the years, resisting western influence as much as possible, and the video below is how a typical Ogene music sounds.
4. EGEDEGE
Egedege is that one style of music that moves everyone to their feet. Egedege is said to have originated from Unubi in Anambra State with Queen Theresa Onuoha as the face of this style of music. Egedege tends to talk about existential social issues with the Oja, Aro and Udu as the chief instruments. Egedege also has its own peculiar dance moves, very thrilling moves that is not found any other place.
5. REGULAR HIGHLIFE
The regular Igbo highlife has experienced a great level of modifications over the years, and so it may be difficult to define what highlife is and what it isn’t. However, in various parts of Igboland, people do this Highlife in different ways. There is Bongo in Imo state, Odumodu in Abia, among others. The video below shows examples of popularly accepted highlife.
6. EGWU ULE/UNE/URE
Egwu Ule is seen as a variation of Egwu Ekpili. The major difference lies in the pace of both styles. While Ekpili is slow, Ule is a bit past-paced.
