Flute arrangement has a listener (3)
I believe the answer is:
ear
'a listener' is the definition.
(body part which hears or listens)
'flute arrangement has' is the wordplay.
'has' indicates the answer is hidden within the clue.
'EAR' is hidden in the letters of 'flute arrangement'.
(Other definitions for ear that I've seen before include "Part of cereal plant containing seed" , "Auditory organ" , "Attention; an organ" , "Organ inside heart" , "See 8" .)
