Indian instrument (5)
I believe the answer is:
sitar
'indian instrument' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sitar that I've seen before include "Astir with Indian long-necked lute" , "instrument out east" , "Guitar-like instrument" , "Long-necked musical instrument of India" , "music-maker" .)
