Musical instrument for us in curiously ambient surroundings (10)
I believe the answer is:
tambourine
'musical instrument' is the definition.
(tambourine is a kind of musical instrument)
'for us in curiously ambient surroundings' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
'for us' could be 'our' ('our' means belonging to us) and 'our' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tambourine that I've seen before include "Shaken instrument" , "One uses jingles" , "drum" , "Percussion instrument" .)
