Early harp
I believe the answer is:
lyre
'early harp' 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 musical instrument - sounds mendacious" , "Ancient Greece harp" , "used to produce music" , "Old musical instrument with strings in U-shaped frame" , "Old stringed instrument" .)
