Navajo children's songs are usually about animals, such as pets and livestock. Some songs are about family members, and about chores, games, and other activities as well. It usually includes anything in a child's daily life. A child may learn songs from an early age from the mother. As a baby, if the child cries, the mother will sing to it while it's tied in the cradleboard. Navajo songs are rhythmic, and therefore soothing to a baby. Thus, songs are a major part of Navajo culture.
It may have been a kind of beginner's course in learning the songs and prayers for self-protection from bad things, skinwalkers, and other evil figures in Navajo traditions. Blessings, such as when one does with corn pollen in the early morning, may be learned as well.
In children's songs, a short chant usually starts off the song, followed by at least one stanza of lyrics, and finishing up with the same chant. All traditional songs include chants, and are not made up solely of lyrics. There are specific chants for some types of songs as well. Comtemporary children's songs, however, such as Christmas songs and Navajo versions of nursery rhymes, may have lyrics only. Today, both types of songs may be taught in elementary schools on the reservation, depending on the knowledge and ability of the particular teacher.
In earlier times, Navajo children may have sung songs like these to themselves while sheepherding, to pass the time. Sheep were, and still are, a part of Navajo life. Back then, giving a child custody of the entire herd was a way to teach them leadership and responsibility, for one day they would probably own a herd of their own. A child, idle while the sheep grazed, may sing to pass the time.
