Creator of dance routines (13)
I believe the answer is:
choreographer
'creator of dance routines' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for choreographer that I've seen before include "One skilled in arranging dances" , "One who creates dance routines" , "Isadora Duncan" , "Composer of ballet steps" , "One arranging dance routines" .)
