Appropriately for Kundry "the Devil's bride", Wagner characterises her by the tritone, the "diabolus in musica" (which in the Ring was associated with Hagen). Occurrences in the example are shown in red. The descending runs in this theme can suggest diabolical laughter, but on its first appearance, they seem to be suggesting Kundry sliding from her horse, reeling, almost collapsing from exhaustion. The complete theme ends with a development of the Yearning motif (A).
For Lorenz it was obvious that this motif had been developed from the lowest voice of the Riding motif (#7), specifically the descending cello phrase in bars 204 and 205, 3rd and 4th beats. With a change of rhythm and extending the arpeggio downwards, it becomes the 6-note germ cell from which Kundry's Laughter develops in its various forms.
