Composer capturing romance in various airs (7)
I believe the answer is:
salieri
'composer' is the definition.
(Antonio Salieri)
'romance in various airs' is the wordplay.
'romance' becomes 'lie' (I've seen this in other clues).
'in' indicates putting letters inside.
'various' indicates an anagram.
'airs' with letters rearranged gives 'sari'.
'lie' put into 'sari' is 'SALIERI'.
'capturing' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
(Other definitions for salieri that I've seen before include "musician accused of murder" , "Composer contemporary with Mozart" , "Italian composer" , "Rival of Mozart" .)
