Terpsichore

"In Greek mythology, Terpsichore (/tərpˈsɪkəriː/; Τερψιχόρη, "delight in dancing") is one of the nine Muses and goddess of dance and chorus. She lends her name to the word "terpsichorean" which means "of or relating to dance". She is usually depicted sitting down, holding a lyre, accompanying the dancers' choirs with her music. Her name comes from the Greek words τέρπω ("delight") and χoρός ("dance"). She was also said to be the mother of the Sirens and Parthenope by Achelous. In some accounts, she bore the Thracian king Biston by Ares." - (en.wikipedia.org 03.01.2021)
