A four-minute bloom in C minor pentatonic. Three voices running a 3:5:7 polyrhythm — triangle in threes, sine in fives, square in sevens — over a single sawtooth root on C2. No drums, no downbeat; the groove is the math. Every low-pass filter is multiplied by a 120-cycle triangle wave, so the whole piece slowly opens from warm and muffled to bright and ringing, then closes again. One long breath in, one long breath out. Let it run for at least three minutes.
