Music-maker’s poetic invocation of lover in recital? (4)
I believe the answer is:
oboe
'music-maker's poetic invocation' is the definition.
I can't judge whether this definition defines the answer.
'of lover in recital?' is the wordplay.
'of' becomes 'o''.
'lover in recital?' becomes 'boe' (I can't explain this - if you can you should believe this answer much more).
'o'+'boe'='OBOE'
(Other definitions for oboe that I've seen before include "Double-reed woodwind" , "Double-reed wind instrument" , "it's blown" , "Instrument used in 1d" , "Source of music" .)
