Might their music produce boos out East? (5)
I believe the answer is:
oboes
'might their music' is the definition.
I can't judge whether this definition defines the answer.
'produce boos out east?' is the wordplay.
'produce' is an anagram indicator (I've seen 'produced' mean this).
'out' is an insertion indicator.
'east?' becomes 'e' ('E' can be a synonym of 'east').
'boos' is an anagram of 'obos'.
'obos' going around 'e' is 'OBOES'.
Can you help me to learn more?
(Other definitions for oboes that I've seen before include "Reed instruments" , "They're instrumental" , "noted producers" , "members of orchestra" , "Woodwind instruments" .)
