Piece from speaker I love (8)
I believe the answer is:
oratorio
'piece' is the definition.
(I have seen 'piece of music' mean 'oratorio' so perhaps 'piece' could also mean 'oratorio')
'speaker i love' is the wordplay.
'speaker' becomes 'orator' (orator is a kind of speaker).
'love' becomes 'o' (love means zero in tennis).
'orator'+'i'+'o'='ORATORIO'
'from' is the link.
(Other definitions for oratorio that I've seen before include "Sung composition based on a religious theme" , "Large-scale choral work" , "I, too, roar at sacred music" , "Handel's Messiah, for example" , "religious music" .)
