Music was performed during funerals ("Tero buru"), to praise the departed, to console the bereaved, to keep people awake at night, and to express pain and agony. It was also used during cleansing and chasing away of spirits. Music was also played during ceremonies like beer parties ("Dudu, ohangla dance"), welcoming back the warriors from a war, during a wrestling match ("Olengo"), during courtship, etc. Work songs also existed. These were performed both during communal work like building, weeding, etc. and individual work like pounding of cereals, or winnowing. Music was also used for ritual purposes like chasing away evil spirits "(nyawawa)", who visit the village at night, in rain making, and during divination and healing. The Luo music was shaped by the total way of life, lifestyles, and life patterns of individuals of this community. Because of that, the music had characteristics which distinguished it from that of other communities. This can be seen, heard, and felt in their melodies, rhythms, mode of presentation and dancing styles, movements, and formations. The melodies in Luo music were lyrical, with a lot of vocal ornamentations. These ornaments came out clearly, especially when the music carried an important message. Their rhythms were characterized by a lot of syncopation and acrusic beginning. These songs were usually presented in solo-response style, although some were solo performances. The most common forms of solo performances were chants. These chants were recitatives with irregular rhythms and phrases, which carried serious messages. Most of the Luo dances were introduced by these chants. One example is the dudu dance. Another unique characteristic in the Luo music is the introduction of yet another chant at the middle of a musical performance. The singing stops, the pitch of the musical instruments go down and the dance becomes less vigorous as an individual takes up the performance is self-praise. This is referred to as Pakruok. There was also a unique kind of ululation, Sigalagala, that marked the climax of the musical performance. Sigalagala was mainly done by women. The dance styles in the Luo folk music were elegant and graceful. They involved either the movement of one leg in the opposite direction with the waist in step with the syncopated beats of the music or the shaking of the shoulders vigorously, usually to the tune of the nyatiti, an eight-stringed instrument. Adamson (1967) commented that Luos clad in their traditional costumes and ornaments deserve their reputation as the most picturesque people in Kenya.
