few months to complete. In some areas, a stone cave may be found that is large enough to accommodate a whole family. A wood-carved effigy, called Tau tau, is usually placed in the cave looking out over the land. Whilst a coffin of a baby is embedded into a burrow of a living tree, so called "baby tree". In the ritual called Ma'Nene, that takes place each year in August, the bodies of the deceased are exhumed to be washed, groomed and dressed in new clothes. Dance and music Torajans perform dances on several occasions, most often during their elaborate funeral ceremonies. They dance to express their grief, and to honour and even cheer the deceased person because he is going to have a long journey in the afterlife.

During the funeral, elder women perform the Ma'katia dance while singing a poetic song and wearing a long feathered costume. The Ma'akatia dance is performed to remind the audience of the generosity and loyalty of the deceased person. After the bloody ceremony of buffalo and pig slaughter, a group of boys and girls clap their hands while performing a cheerful dance called Ma'dondan.
