Times for musicians in the Stockport Empire (5)

I believe the answer is:
tempi
'times for musicians' is the definition.
'tempi' can be an answer for 'times' (I've seen this before). I am not sure about the 'for musicians' bit.
'in the stockport empire' is the wordplay.
'in' says the answer is hidden in the clue.
'TEMPI' is hidden within 'stockport empire'.
Can you help me to learn more?
(Other definitions for tempi that I've seen before include "Times" , "Speed controls" , "Speeds for musicians" , "Speeds (music)" , "Rates" .)
