What is a terpsichory?

Question

Paul McCartney writes that his song has a "terpsichory", which I think is like an instrumental break. However, I can't find any definitions on the internet.

Help!

Answer 1

Right on!

He was obviously  referring  to Terpsichore ,the muse of dance.

Therefore, I would assume Paul meant that his song inspired you to dance.

A remark fitting of Paul's genius.

Answer 2

Terpsichory was the Greek muse of dance ~

Answer 3

It is a Greek Muse: in Greek mythology, the Muse of choral songs and dance, one of the nine Muses believed to inspire and nurture the arts

Hope that helps.
