Document Summary
Variable intervals in a pentatonic scale as used by the bedzan pygmies of central cameroon. The double-headed arrow inside the white box indicates the minimum size of the interval and the arrow extending into the gray boxes indicates the maximum size of the interval. The overlapping gray boxes for adjacent intervals and for higher level intervals shows how changing one interval has to result in changes in the other interval(s) within the maximum and minimum constraints. So the actual intervals can be different, but the relative sizes of the intervals must conform to the global constraints. 4 voice ranges: voice of big (men), voice of young men, voice of (big) women, voice of small (children) They sing a capella multi-part polyphonic textures that are metric, cyclical, and based on an ostinato figure with variations. There is no absolute pitch for a given piece, and the intervals that separate the various scale degrees of the song are not stable.
