一狂 Set Analysis - Andante section

Recap ...

Materials found in the introduction:

In the succeeding Andante section, I found some recurrences of these materials at different transpositional intervals and at times, slightly altered by expansion and diminution.

As seen in the scores above, [0, 3, 4, 7] is used frequently, both melodically and harmonically, with subset – superset relation, inversional, transpositional relation.

The largest set {0, 1, 3, 4, 5, 7, 9} containing the subsets [0, 3, 4, 7] and [0, 1, 4, 5, 9] is found at the end of the melodic phrase (bars 16-20) and this is further enlarged in bars 21-22 into {0, 1, 3, 4, 5, 7, 8, 9}, when the melodic role is passed to the accompaniment.
