Is it tuned a bit sharp? (4)
I believe the answer is:
harp
'is it tuned a bit' is the definition.
I can't tell whether this defines the answer.
'sharp?' is the wordplay.
'HARP' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for harp that I've seen before include "Keep on about" , "Instrument for angel" , "Talk tiresomely using upright musical instrument" , "Traditional Gaelic musical instrument" , "Stick to one theme" .)
