Maurer (1995: 10–23) offers a very preliminary analysis of the tone system of Angolar, which has to be seriously amended.
My 2008 data improve the analysis only very basically.
The audio files show disyllabic nouns in subject position followed by the future marker ka; the verbs are different but since they exhibit the same tonal structure, the frame for the disyllabic nouns can be considered the same.
