In traditional African culture, music has ritual, social, and ceremonial functions along with some solely recreational functions. Musical activities are highly ritualized and are considered to link the invisible world with the visible world. Melodies are generally organized within a scale of four, five, six, or seven tones. Musical instruments in Africa take on sculptural forms that are sacred, elaborate, simple, humorous, and serious, or a combination of all. Irrespective of whether these musical instruments are beaded, carved, painted, or decorated with skins, they send messages about the religious beliefs, artistic styles, and entertainment practices of the people who made them.
