"The Music Man" locale (4)
I believe the answer is:
iowa
'the music man locale' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iowa that I've seen before include "US state, capital Des Moines" , "State of USA" , "American state, capital Des Moines" , "'Hawkeye State'" , "Midwest US state" .)
