Music by Allen Fogelsanger Allen Fogelsanger

Canon by two pairs of oscillators; in each pair one oscillator modulates the other. Although they are carefully tuned they are subject to small random changes in frequency. Each oscillator produces notes by subjection to amplitude envelopes repeatedly sent from its own dedicated envelope generator. The progression of the piece is simple. In the beginning the envelopes have sharp attacks and randomly long decays. The decays are gradually shortened (though are still of random duration). Finally the attacks are lengthened. And lengthened more. Composed April 27, 2013, New York.
