Predict how violin may be played on the radio (4)
I believe the answer is:
bode
'predict' is the definition.
('bode' can be a synonym of 'predict')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bode that I've seen before include "Portend, foretell" , "Augur (well, badly)" , "predict" , "Waited" , "Presage" .)
