A phasing study in E minor, after Steve Reich's Piano Phase. Three voices play the same 8-note melody (E G B A G E G B) at nearly-identical tempi: 30, 30.075, and 30.15 cycles per minute. They start in unison. Voice 2 (in E3) drifts one full phase revolution against voice 1 every ~13 minutes. Voice 3 (in E5) drifts twice as fast, ~6.7 minutes per revolution. So at any moment you hear the SAME melody at three different phase positions AND three different octaves — like the melody echoing through a stairwell that's very slowly rotating. No percussion, no filter sweeps, no probabilistic modifiers. Just three lines, one drone, and time itself as the compositional agent.
