Acrobatic dancers lead off the choral singing and dancing, and the khoros or ‘place for choral singing-and-dancing’ becomes their dancing floor. This pattern of leading off resembles the pattern we see in versions of Ο.04.019 and Ι.18.606 where we see the variant reading ἐξάρχοντες instead of ἐξάρχοντος. In terms of this reading, the acrobatic dancers lead off, starting their performance before the singer starts.
