Example 11. Chiastic structure embedded in the solo part for player B in mm. 16–17. The red numbers indicate the position of each sixteenth note relative to the beginning of m. 16. The yellow rectangles reflect thematic similarity based on sporadic deviations of timbres from the uppermost line. The two sixteenth notes in green boxes surround the core of the chiasmus, indicated by the red box. The purple line and the number below represent the total number of sixteenths before and after the red segment (14).
