The note operations in this period are exclusively note additions. The rhythmic density is raised over the period from 8ths to 32nd triplets, using almost the entire rhythmic spectrum between these two extremes. One exception where the rhythm is augmented shortly is the transition between measures 162 and 163. Dynamics evolve in crescendo from pianissimo in measure 151 towards forte in measure 168. Accents are added to enhance the structure and direction of the constructive period. The phrasing starts with full pedals and evolves through a combination of staccato non-pedal and 1/2 pedal, to end in only 1/2 pedal. The melodic curve starts from the quite fluent stretched main motif head, goes through a capricious part in measures 163-166 and ends in a quite fluent curve in motif 5. 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.
