Composer's address in Wales (4)
I believe the answer is:
bach
This clue might be a double definition.
'composer's' is the first definition.
(Johann Sebastian Bach)
'address in wales' is the second definition.
'bach' can be an answer for 'address' (I have seen 'Affectionate address' mean 'bach' so perhaps 'address' could also mean 'bach'). I'm not certain of the 'in wales' bit.
Can you help me to learn more?
(Other definitions for bach that I've seen before include "Brandenburg Concertos composer, d. 1750" , "German organist and composer, d. 1750" , "Welsh term of endearment" , "German composer (affectionate to a Welshman?)" , "Affectionate address" .)
