The slow square beat is already in place, with a low tone holding underneath it.

Here's the first vocal entrance: "Polarlicht" lands inside the beat, more like a named light than an explanation.

When she sings "Scheine, scheine," the command is cool, but it has bite against the plain drums.

The title comes back quickly, and the repetition starts to make the word feel fixed in the distance.

Listen to the low end gather under the beat, then ease off without breaking the walk of the song.

This "Polarlicht" rises out of a small lift in the band; after so much repetition, even that little rise clears the ear.

The title hangs longer here, and the top of the sound starts to flicker more roughly around it.

"Aura am Nachthimmel" opens the lyric upward, but the night sky still has the same beat underneath it.

The returning "Polarlicht" doesn't need a bigger arrangement; the song has made the repetition do the work.

There's a small loosening now, then the weight gathers back instead of turning into a new section.

Just before the last words, the pattern starts giving way; the final "Scheine, scheine" glows after the groove has begun to drain.

The ending recedes in pieces: loosened beat, interrupted surface, and that shine left behind.
