No certain criteria. The girl dances about her experience of being branded.

BRAND DANCE

The Brand Dance is not really expanded upon in the books. One would assume that this dance would be performed by a girl just before her branding, perhaps begging for the kiss of the heated iron. Or, too, this dance could be performed afterwards, the slave girl expressing what the brand means in her absolute submission.

“Already a large, curtained enclosure had been set up near the slave wagon. For a fee, the proprietor of the wagon would permit visitors. These arrangements irritated me somewhat, for customarily the chain dance, the whip dance, the love dance of the newly collared slave girl, the brand dance, and so on, are performed openly by firelight in the evening, for the delight of any who care to watch.”
