Layered with a darbuka playing a driving but relaxed rhythm, shakers, and hand percussion. A ney flute enters with a melancholic melody. Deep sub bass pulses underneath. A baglama/saz plays a sparse, atmospheric figure. Use warm analog tape saturation, spacious reverb, and subtle echo effects. No vocals. Build slowly, with a sense of nocturnal travel across dunes.",
