Falling up the down escalator emphasizes the differences between the four instruments in the ensemble. The first section on the octave that is common to all of the instruments, pitting their timbres against one another in continuous motion.

After gaining its own momentum, it is overtaken by the frantic, circular motion of the opening, this time in the opposite direction.
