Listen to soprano during physical exercise (9)
I believe the answer is:
rehearsal
'exercise' is the definition.
(rehearsal is a kind of exercise)
'listen to soprano during physical' is the wordplay.
'listen to' becomes 'hear' (I've seen this before).
'soprano' becomes 's' (musical abbreviation).
'during' is an insertion indicator.
'physical' becomes 'real' (I've seen this in other clues).
'hear'+'s'='hears'
'hears' put within 'real' is 'REHEARSAL'.
(Other definitions for rehearsal that I've seen before include "Play run-through" , "Dummy run" , "Dramatic practice" , "Dry run" , "Practice - run-through" .)
