Static instrumental loop for a game background, 120 BPM, 4/4, no vocals. The SAME two-bar ostinato repeats unchanged from the first second to the last: identical instrumentation throughout, constant density, constant volume. Deep sub-bass pulse, steady kick on every quarter, low tribal toms, sustained strings pad, simple 8-note motif on a hybrid synth-flute. STRICTLY NO introduction, no build-up, no crescendo, no drop, no breakdown, no risers, no filter sweeps, no instruments entering or leaving, no ending. Every bar must be interchangeable with every other bar.
