A piece from Salieri sent up (5)
I believe the answer is:
risen
'up' is the definition.
(similar in meaning)
'a piece from salieri sent' is the wordplay.
'a piece from' says the answer is hidden in the clue.
'RISEN' can be found hidden inside 'salieri sent'.
(Other definitions for risen that I've seen before include "Suggestive of soil" , "stirred" , "(Of sun) up" , "Climbed" , "Ascended - revolted" .)
