Why did Polynesian cultures preserve chants, legends, songs, and spells over many generations?

In Polynesian cultures, the preservation of chants, legends, songs, and spells was essential for maintaining the social, religious, and historical fabric of society. These oral traditions served several critical functions:

• Validation of Social Structure: Music and dance acted as vehicles for praising high-ranking chiefs, validating their genealogical rank, and recounting their descent from the gods.1
• Religious and Supernatural Practice: Religious concerns permeated all aspects of life, and chants were vital for worshipping gods and spirit-beings. Because mana—a sacred supernatural power—could be influenced by human actions, certain chants and spells required precise pronunciation to avoid violating taboos or to ensure success in endeavors like war, fishing, and planting.2
• Cultural Heritage and Education: Oral traditions, such as Maori oriori (songs for children), were used to teach younger generations about their heritage and tribal history.3
• Connection to the Past: Legends did not merely recount the past; they brought historical events and ancestral deeds into the present, making them contemporary and relevant to the community's current needs.3
