Reynard's enemy is initially enjoying music over Ring cycle (8)
I believe the answer is:
isengrim
'reynard's enemy' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'is initially enjoying music over ring cycle' is the wordplay.
'initially' suggests taking the first letters.
'over' means one lot of letters goes inside another.
'cycle' is an anagram indicator.
The initial letters of 'enjoying music' is 'em'.
'ring' with letters rearranged gives 'ngri'.
'em' going around 'ngri' is 'engrim'.
'is'+'engrim'='ISENGRIM'
Can you help me to learn more?
(Another definition for isengrim that I've seen is " Wolf's name in the tale of Reynard the fox; I'm singer (anagram)".)
