Minimal techno, 126 BPM, minor key. Dry, tight kick with a short tail and no boom. Very sparse hi-hats: only occasional off-beat hits, not constant rolls. Sub-bass that’s felt more than heard, no dominant bassline melody. Main melodic element: one single arp line with a slightly detuned, “gritty” analog feel; it repeats with tiny variations every 8 bars. Add subtle noise textures and tape-hiss-like layers as a background element. Use long reverb on the arp to create space, but keep the kick and bass dry. No big build-ups or drops; tension comes from the slow evolution of the arp and the noise layer getting slightly denser. Track length under 4 minutes, fade-out after the last arp variation.
