How are recitatives different from public orations in Oceanic oral traditions?

In the context of Oceanic oral traditions, the primary distinction between recitatives and public orations lies in their level of formal flexibility and the speaker's freedom to adapt the content.1

• Recitatives: These are formally rigid texts, such as songs or chants accompanying dances, funeral chants, or those related to games and erotic themes. While they may be expanded, they cannot be transformed. They are characterized by a strictly unvarying manner of communication, often relying on memory aids like rhythm and stock formulas to maintain their structure.1
• Public Orations: These discourses, which include political speeches, eulogies, and commemorations of life stages, are organized in a more rough and flexible manner. They grant the speaker the authority to vary the presentation within established limits. This flexibility allows the orator to introduce nuances that reflect the current social or political context, such as declaring peace or marking a new stage in a political career, with the success of the speech often measured by the accord reached between the speaker and the audience.12
