Repeatedly varied Paganini piece (5)
I believe the answer is:
again
'repeatedly' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for again that I've seen before include "second term" , "On the other hand" , "Repeatedly" , "One more time, encore" , "Ocne more" .)
