Keep away from the chorus ... (7)
I believe the answer is:
refrain
This clue could be a double definition.
'keep away' is the first definition.
'refrain' can be an answer for 'keep' (thesaurus). I'm unsure of the 'away' bit.
'chorus' is the second definition.
(synonyms)
'from the' acts as a link.
Can you help me to learn more?
(Other definitions for refrain that I've seen before include "Do without" , "Main theme" , "Musical phrase" , "Much repeated saying" , "Recurring music to forbear from" .)
