sentences:  Trope 3 also allows the creation of an intertwined retrograde transposition by a major second and therefore of trope 17 (e.g., G-A-C-B-F-F-|-E-E-C-D-B-A → Bold pitches represent a hexachord of trope 17) .In general, familiarity with the tropes enables a composer to precisely predetermine a whole composition according to almost any structural plan.For instance, an inversional twelve-tone row from this trope 3 (such as G-A-C-B-F-F-D-C-A-B-E-D) that is harmonized by the [3-3-3-3] method as suggested by Hauer, will result in an equally inversional sequence of sonorities.
