What’s sung with love for each note (5)
I believe the answer is:
opera
'what's sung' is the definition.
(an opera is sung)
'with love for each note' is the wordplay.
'with' means one lot of letters go next to another.
'love' becomes 'o' (love means zero in tennis).
'for each' becomes 'per' (per person).
'note' becomes 'a' (musical note).
'o' put next to 'per' is 'oper'.
'oper'+'a'='OPERA'
(Other definitions for opera that I've seen before include "Eg, Don Giovanni" , "Musical piece accompanying a stage drama or comedy" , "10 [NORMA], for example" , "Staged event" , "Musical works" .)
