120 BPM, 4/4, instrumental, no vocals with words. LOOP STRUCTURE: the piece is ONE self-contained 16-bar phrase that repeats over and over, returning to exactly the same material each cycle — like a strategy game map theme on endless repeat. Rich harmonic and melodic movement WITHIN the phrase is wanted: counterpoint, moving inner voices, a real melody with an answer. But the FULL arrangement is present from the very first bar and stays: no thin intro, no gradual layering, no build-up, no crescendo to a climax, no breakdown, no final chord, no ritardando, no fade. Overall energy and density identical at the start and at the end. XCOM geoscape theme: slow ominous brass swells over a cold electronic pulse, ticking percussion, sparse piano notes, deep sub drone, analytical and foreboding sci-fi.
