New tsar of music and dance (4)
I believe the answer is:
arts
'music and dance' is the definition.
(I've seen this in another clue)
'new tsar' is the wordplay.
'new' indicates anagramming the letters.
'tsar' with letters rearranged gives 'ARTS'.
'of' acts as a link.
(Other definitions for arts that I've seen before include "Eg, painting, sculpture" , "Wiles, skills" , "Poetry, music, painting etc." , "Drawing, painting, etc" , "Tricks" .)
