Recollection of passage from intermezzo, so romantically, tenderly played (7)
I believe the answer is:
amoroso
'tenderly played' is the definition.
(musical direction)
'recollection of passage from intermezzo so romantically' is the wordplay.
'recollection of' says the letters should be written backwards (recollect letters in the opposite direction).
'passage from' says the answer is hidden in the clue (a sequence or passage of letters from the clue).
'osoroma' is hidden in the letters of 'intermezzo so romantically'.
'osoroma' reversed gives 'AMOROSO'.
(Other definitions for amoroso that I've seen before include "Lovingly (music); sherry" , "lovingly expressed" , "tenderly" , "Loving, tender (in music)" , "Dark sweet sherry" .)
