Music producer hurt over in eastern California (9)
I believe the answer is:
harmonica
'music producer' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'hurt over in eastern california' is the wordplay.
'hurt over' becomes 'harmo' (I can't explain this - if you can you should believe this answer much more).
'eastern' shows that the letters should be reversed in order (letters written right to left or east to west).
'california' becomes 'ca' (abbreviation).
'in' backwards is 'ni'.
'harmo'+'ni'+'ca'='HARMONICA'
Can you help me to learn more?
(Other definitions for harmonica that I've seen before include "Blow me!" , "glasses of water" , "It's blown" , "An alternative mouth-organ" , "Mouth organ" .)
