Once again, the q motive is heard, only this time the register is quite low. In fact, the opening pitch low B is the lowest pitch heard thus far in the movement. The tremolos continue and the sound soon thickens as both hands play chords stretching an octave or wider. This section offers contrast in that it reaches a dynamic height of fff and stays there for two measures. The repeating octaves in mm.101-104 are reminiscient of the closing of the A section.
Sessions increases the anticipation by delaying the return of the A section.
The rallentando and Tempo I markings help to signify the return to the A section. This section is again linear, for the most part, with the exception of mm.155-160. Roger Sessions was a composer who struggled to notate his music. In the early years of his career, he refrained from writing specific indications for fear the performer would exaggerate the gesture. Written in 1946, the Second Piano Sonata contains precise instructions for tempo, phrasing, dynamics and articulation.
