Where bars are not sweet music (6)
I believe the answer is:
prison
This clue could be a double definition.
'where bars' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'not sweet music' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'are' is the link.
Can you help me to learn more?
(Other definitions for prison that I've seen before include "Jail" , "Place of incarceration" , "porridge" , "cage" , "Clink - jug" .)
