"The Nutcracker," for one (6)
I believe the answer is:
ballet
'the nutcracker for one' is the definition.
(I know that The Nutcracker is a ballet)
This is all the clue.
(Other definitions for ballet that I've seen before include "Type of dance" , "Artistic dance form" , "Theatrical entertainment" , "The Nutcracker or Giselle, say" , "kind of skirt" .)
