[Opening: Absolute silence, then a single isolated piano note. No other sounds.] [Low Strings: After a few seconds, deep sustained cello and double bass tones slowly emerge. One continuous ominous sound, no melody.] [Low Brass: A few seconds later, low bass trombone and tuba enter gradually, following the strings. Deep sustained tones overlap and build tension.] [Alarm Piano: The piano suddenly begins a sharp, repetitive, alarm-like pattern. The low strings and brass continue underneath.] [Ending: The strings and brass stop completely. Only the repeating alarm-like piano remains. The piano alone slowly fades into absolute silence.] [End: No additional notes, no extra section, no outro, no reverb tail after silence.]
