Accepted / Refused

Simha Arom, Suzanne Fürniss submit to a group of Aka Pygmies short pieces of music played on the synthesizer, asking them to accept or refuse various renditions modulating the system of intervals according to their suitability for the traditional polyphonic repertoire.
They are offered three types of tests:
- the partita, where a polyphony alien to the Aka's is used to make them distinguish the parameters of form, part and timbre before considering the actual musical scales.
- the chaconne with scalar variations, where by submitting to the Aka a piece of their polyphonic repertoire whose system of intervals is modulated at each performance, they are invited to accept or refuse each of the proposed renditions.
- transfigurations, where we discover that, in aka polyphonic conduct, following the order of succession of melodic degrees prevails over the length of intervals.
