Award describing second letter from Soul Music producer (4)
I believe the answer is:
oboe
'music producer' is the definition.
(I've seen this before)
'award describing second letter from soul' is the wordplay.
'award' becomes 'OBE' (Order of the British Empire).
'describing' means one lot of letters goes inside another (describe can mean to form the outline of).
'second letter from soul' becomes 'o' (2nd letter of 'soul').
'obe' enclosing 'o' is 'OBOE'.
(Other definitions for oboe that I've seen before include "Woodwind instrument of treble pitch" , "Double-reed wind instrument" , "Musical instrument" , "Instrument used in 1d" , "it's blown" .)
