A test to see the different formations of the inner cavity of the mouth and duplications of the full object. When you begin to add more faces it starts to create the effect of a choir, also by adding more faces the gender of each becomes more and more blurred and it will be interesting to test this when there are different faces involved. The notion of the removal of gender is akin to the cyborg theory and the manipulation of the voice, with things such as auto-tune, will again remove the clear boundaries of gender that we currently perceive.

The formation of the faces in either groups of three,  to create a chord, or groups of twelve, to create an octave. Or four groups of three as a combination of both. Then the different speakers can be set up to output a certain note and manipulate the voice as it is fed through it.
