Within the animist belief system of Indigenous Australians, a songline, also called dreaming track, is one of the paths across the land (or sometimes the sky) which mark the route followed by localised "creator-beings" during the Dreamtime. The paths of the songlines are recorded in traditional songs, stories, dance, and painting.
A knowledgeable person is able to navigate across the land by repeating the words of the song, which describe the location of landmarks, waterholes, and other natural phenomena. In some cases, the paths of the creator-beings are said to be evident from their marks, or petrosomatoglyphs, on the land, such as large depressions in the land which are said to be their footprints.
By singing the songs in the appropriate sequence, indigenous people could navigate vast distances, often travelling through the deserts of Australia's interior. The continent of Australia contains an extensive system of songlines, some of which are of a few kilometres, whilst others traverse hundreds of kilometres through lands of many different indigenous peoples — peoples who may speak markedly different languages and have different cultural traditions.
Since a songline can span the lands of several different language groups, different parts of the song are said to be in those different languages. Languages are not a barrier because the melodic contour of the song describes the nature of the land over which the song passes. The rhythm is what is crucial to understanding the song. Listening to the song of the land is the same as walking on this songline and observing the land.
In some cases, a songline has a particular direction, and walking the wrong way along a songline may be a sacrilegious act (e.g. climbing up Uluru where the correct direction is down). Traditional Aboriginal people regard all land as sacred, and the songs must be continually sung to keep the land "alive".
Molyneaux and Vitebsky note that the Dreaming Spirits "also deposited the spirits of unborn children and determined the forms of human society," thereby establishing tribal law and totemic paradigms.
In his 1987 book The Songlines, British novelist and travel writer Bruce Chatwin describes the songlines as:
... the labyrinth of invisible pathways which meander all over Australia and are known to Europeans as "Dreaming-tracks" or "Songlines"; to the Aboriginals as the "Footprints of the Ancestors" or the "Way of the Lore".
