Cinematic electronic music, deep space. Distant view of a black hole, slow descent. Metronome ticks very slowly and quietly at first. As you approach, the metronome becomes louder. Music swells between the clicks — louder each time between beats, then drops quieter exactly on the metronome hit, then rises again. Each cycle louder than the last. Eventually the metronome beats and the music merge completely. Final stage: several instruments play together with the clicks — ethereal synths, deep bass, granular textures. Slow tempo, building dread.
