Music for performance with love (8)
I believe the answer is:
concerto
'music' is the definition.
(concerto is a kind of music)
'performance with love' is the wordplay.
'performance' becomes 'concert' (concert is a kind of performance).
'with' says to put letters next to each other.
'love' becomes 'o' (love means zero in tennis).
'concert'+'o'='CONCERTO'
'for' acts as a link.
(Other definitions for concerto that I've seen before include "Work for soloist and orchestra" , "Composition for orchestra and soloist" , "Musical composition" , "Composition for orchestra in several movements" , "Orchestral piece" .)
