Accompanies one on a sunny day to perform a form of East Asian drama (6,4)
I believe the answer is:
shadow play
'accompanies one on a sunny day to perform a form' is the definition.
I can't tell whether this defines the answer.
'east asian drama' is the wordplay.
'east asian' becomes 'shadow' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'drama' becomes 'play' (synonyms).
'shadow'+'play'='SHADOW-PLAY'
'of' acts as a link.
Can you help me to learn more?
(Another definition for shadow play that I've seen is " outlined performance".)
