Although the period is marked as “constructive,” the note operations consist of a combination of both note-additions and note-diminutions. The rhythmic density is raised over the period from 16ths over quintuplets and sextuplets to 32nds towards the middle of the period. Dynamics evolve in crescendo from piano in measure 116 to fortissimo in measure 132. Accents are added to enhance the structure of the constructive period. The phrasing remains 1/2 pedal throughout the period, except for the beginning of the period at measure 116, which is marked with a full pedal. The melodic curve starts from the very capricious repetitive measure 116 and continues to be quite jumpy into motif 4. The construction of this period holds a very clear rotation: the order of the notes remains the same, but their position within the bar changes.
Bar 116 is played with a full pedal (changing the pedal every repetition) and gradually evolves into quasi-secco playing in measure 121 where the accents are added. To clarify the rhythmic transformation over the change of 16th notes into 32th notes - via quintuplets and sextuplets - the phrasing should be consistent. For the complete following passage, the pedal focus should be on the accentuated notes. The smoother that the transition in the pedaling is executed, the more the structure of the piece comes to the foreground.
