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