What does くるりと回れば means? Is this some kind of expression?

The old woman is recalling what her daughter said before leaving the village.
I understand

> 中の者も 外の者も関係ない

"Whatever it's a person from inside the village or outside it doesn't matter"

> 神楽や歌にはその力がある

"Such power exists inside the kagura and the dance."

However what I'm stumbled is the middle sentence

> くるりと回れば 1つになる

"1つになる" may be modifying 神楽 and 歌 but I'm not convinced. Likely it may say
that the people outside and inside became one under that power.

However, I'm stumbled of the meaning of くるりと回れば

Either she's talking about the dance she performs, or it's "after seeing the
world" or some nuance I'm missing.

She should be saying that the Kagura and the dance don't discriminate and they
have the power to unify people.




くるりと回る here probably describes certain motion in kagura and thus figuratively
refers to performing kagura. I’m not sure who performs kagura, but the subject
of一つになる is both 中の者 and 外の者. Therefore, the entire sentence means “if someone
performs kagura, both groups of people (villagers and strangers) become
unified.”

My guess is kagura performers are also 中の者 and 外の者, and then it have nuance of
”getting along with each other through performing kagura together.”
