Harplike instrument (4)
I believe the answer is:
lyre
'harplike instrument' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lyre that I've seen before include "Ancient stringed musical instrument with U-shaped frame" , "Ancient Greece harp" , "Old musical instrument with strings in U-shaped frame" , "Ancient Greek harp" , "Old instrument, like a harp" .)
