Tune carried in flight (8)
I believe the answer is:
airborne
'in flight' is the definition.
(I've seen this before)
'tune carried' is the wordplay.
'tune' becomes 'air' (air can mean a piece of music).
'carried' becomes 'borne' (I've seen this before).
'air'+'borne'='AIRBORNE'
(Other definitions for airborne that I've seen before include "Off the ground" , "so, paras?" , "Aloft, flying" , "upwardly mobile" , "Having taken off" .)
