Spirit revealed by music presenter in Beethoven's ninth (5)
I believe the answer is:
djinn
'spirit' is the definition.
(spirit in Islam)
'presenter in beethoven's ninth' is the wordplay.
'presenter' becomes 'dj' (radio DJ).
'beethoven's ninth' becomes 'n' (9th letter of 'beethoven').
'dj'+'in'+'n'='DJINN'
'revealed by music' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for djinn that I've seen before include "Spirit of Arabian mythology" , "Spirit of Arabian legend" , "Mythological spirit" , "Spirits (in Muslim mythology)" .)
