New star of painting and music (4)
I believe the answer is:
arts
'painting and music' is the definition.
(painting and music are examples)
'new star' is the wordplay.
'new' indicates anagramming the letters.
'star' anagrammed gives 'ARTS'.
'of' acts as a link.
(Other definitions for arts that I've seen before include "Aesthetic creations for a star" , "Tricks" , "A degree" , "Aesthetic products for star" , "Products of human creativity" .)
