Terpsichore
Τερψιχόρη
The Muse whose name literally means "delighting in the dance."
Terpsis (delight) + khoros (choral dance): the dance is already inside her name.
She is depicted dancing with a lyre in her hands.
One tradition even makes her the mother of the Sirens — a lineage of sounds that bewitch.
