The "Mouvance III: Distortion" concert did, like a mass, end with an amen, from the end of Dufay's "Nuper rosarum flores". The ensemble 'submerged' before the last chord, they ended with a long subharmonic or shimmer while bringing the instrument for a two minute walk amongst the audience.

A  proportion canon of water bubbles follows the noise. We will soon discuss Ciconias proportion canon. The water bubble texture following the Amen an inverse proportion canon, using the same ratios as our expanded Ciconia canon. The counterparts are slower, rather than faster, than the original.  Bubbles close to a natural speed is the ratio 1:1. This is superposed with bubbles stretched to 3:1, 4:1, 5:1, 7:1 and 9:1. To avoid enourmous files, stretched versions did not contain the whole original. The stretching was done with Audiosculpt. This treatment of sound was inspired by a medieval composition.
