Tremolo from diaphragm, not vibrato.] [Reverb: deep cave-like resonance, long decay, natural stone reflection — like singing inside a mountain] [Primary instrument: didgeridoo (yidaki) in Bb — continuous, breathing, alive. It leads, responds, and governs the rhythm.] [Tempo: 70 BPM — steady, unwavering, no acceleration or ritardando. Pulse like a stone heart. All elements locked to this rhythm.], dubstep, ambient
