Numbers 12 onwards were composed in Italy in the summer of 1907. The whole-tone scale is used for the grand and compelling theme of the piece. A continuous succession of arpeggios expresses intense inner conflict. The arpeggios are constructed by combining sixteenth-note triplets and thirty-second notes. The characteristics of the whole-tone scale, namely "tonal ambiguity" and "unease," dominate the entire piece. The thematic motif is repeated, utilizing a wide range of the keyboard across the middle, high, and low registers for expression.

Furthermore, as Palmgren injured his right middle finger just before arriving in Pesaro, Italy, this piece is written in such a way that it can be performed even without the use of the right middle finger. It is also thought that the dominance of the left-hand arpeggios in the piece was to avoid burdening the right hand.
