A round dance? (4)

I believe the answer is:

ball

I believe this is a double definition.

'a round' is the first definition.
(I've seen this before)

'dance?' is the second definition.
(ball is a kind of dance)

(Other definitions for ball that I've seen before include "Throw a dance" , "form of entertainment" , "Sphere - dance" , "Sphere; function" , "Spherical object" .)

I've seen this clue in the Evening Standard.
