For assignment 4 I took the piece “Pa Pa Papageno” from the opera The Magic Flute and separated the frequencies using a PFFT so that all frequencies within the human vocal range were allocated to one matrix and all other frequencies were allocated to another matrix.  I took these two matrices and used an altered version of the patch from class to create two groups of shapes, green polyhedrons and red cubes. The red cubes fluctuate in size with the orchestra, and the green polyhedrons fluctuate with the opera singers.
