Solo piano enters at once with a fast cascading figure. A steady pulse locks underneath the rolling surface, and the piece’s contract is clear within seconds: perpetual motion carrying a bright melodic thread.

The same motor keeps turning through successive phrase groups. Melodic turns shift register and harmony while the accompaniment never breaks stride; local pressure builds and eases in waves without changing the formal job.

A longer build gives way to release and a brief phrase drop, then the pocket resettles. From about 1:27 the sustained spinning state returns intact—repetition proving the pattern still holds rather than introducing a new design.

Weight lifts and pressure builds again. The piano races upward through runs and bright high figures; near 2:00 the surface hardens while the motor current stays locked, concentrating the form toward cadence.

Pressure opens into firm concluding chords and quick flourishes. The final sustained chord rings and fades; pattern and body lock loosen together, closing the perpetual-motion contract cleanly.

The whole track is one spinning engine proved, varied, and finally landed.
