Gregarious.

As choral singing is intrinsically communal, here is a chant for the word meaning friendly and sociable, and a whole lot more according to the dictionary, which says:(lyrics)

"Gregarious, adjective.

Living in flocks or communities.

Fond of company.

Fond of growing in clusters of flocks, clusters of crowds.

Hence gregariously, adverb,

and gregariousness, noun.

From the Latin gregarius."

We give thanks unto the Oxford Dictionary for this enlightenment.
