Instrument most artists can play? (5)
I believe the answer is:
'instrument' is the definition.
(sitar is a kind of instrument)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for sitar that I've seen before include "Plucked instrument" , "Guitar-like instrument" , "It takes pluck" , "Hindu stringed instrument" , "Indian musical instrument like long-necked lute" .)
