Wind music? (3)
I believe the answer is:
air
This clue is a double definition.
'wind' is the first definition.
(air is a kind of wind)
'music?' is the second definition.
(air is a kind of music)
(Other definitions for air that I've seen before include "in which birds fly around" , "Skye Boat Song, perhaps" , "that's inspired" , "Broadcast; mien" , "put on radio?" .)
