Series. This second block continues to draw from the rows of the R-array. The first two hexachords, from R^A, are related by transposition. Both are related to the third hexachord, from R^B, by inversion. The high C in m. 8 is shared by R^AI and R^AII. The linear order of R^BIII is reflected in the registral order (lowest to highest) of the concluding chord.
