Stradivari creation (6)
I believe the answer is:
violin
'stradivari creation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for violin that I've seen before include "Menuhin's instrument" , "It'a played with a bow" , "Nigel Kennedy instrument" , "Instrument with bow" , "Instrument with four strings" .)
