Synthetic Piece 2 (quadres 31)

This piece is the second in a series based on quadratic residues of a number. If a perfect square of some integer is congruent to some number n mod p, then we say n is a quadratic residue of p. In this piece, the frequencies of the pitches, as well as their envelopes, and significant structural boundaries, are all based on the quadratic residues of 31, and permutations thereof.
