Time final pieces from the chamber orchestra (3)
I believe the answer is:
era
'time' is the definition.
(era is a kind of time)
'final pieces from the chamber orchestra' is the wordplay.
'final pieces from' says to take the final letters.
The final letters of 'the chamber orchestra' are 'ERA'.
(Other definitions for era that I've seen before include "Special time" , "Memorable period" , "Age of importance" , "Age marked by a distinctive character" , "8" .)
