Call to lover overheard in wind? (4)
I believe the answer is:
oboe
'wind?' is the definition.
(I know that oboe is a type of double reed)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for oboe that I've seen before include "Orchestral instrument" , "Orchestral piece" , "bit of wind" , "music producer" , "Source of music" .)
