Cajun music coordinates art style (6)
I believe the answer is:
zydeco
'cajun music' is the definition.
(I've seen this before)
'coordinates art style' is the wordplay.
'coordinates' becomes 'zy' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'art style' becomes 'deco' (I've seen this in another clue).
'zy'+'deco'='ZYDECO'
Can you help me to learn more?
(Other definitions for zydeco that I've seen before include "Cajun music" , "Louisiana music style" , "Music of southern Louisiana" , "dance music" .)
