Dances arranged to scale (6)
I believe the answer is:
ascend
'to scale' is the definition.
(as in scaling a mountain)
'dances arranged' is the wordplay.
'arranged' indicates an anagram.
'dances' anagrammed gives 'ASCEND'.
(Other definitions for ascend that I've seen before include "Gain height" , "Scale" , "Get higher" , "Come up" , "Move upward" .)
