Virtuoso violinist, one with no religion in Italy (8)

I believe the answer is:

paganini

I'm a little stuck... Click here to teach me more about this clue!

'virtuoso violinist' is the definition.
'paganini' can be an answer for 'violinist' (I've seen this before). I am unsure of the 'virtuoso' bit.

'one with no religion in italy' is the wordplay.
'one with' is a charade indicator (letters next to each other).
'no religion' becomes 'pagan' (pagan religion is a kind of religion. I am not sure about the 'no' bit.).
'italy' becomes 'i'.
'pagan'+'in' is 'paganin'.
'paganin'+'i'='PAGANINI'

Can you help me to learn more?

(Other definitions for paganini that I've seen before include "Old bower" , "fellow on the fiddle" , "supposedly devil-inspired virtuoso" , "Violin virtuoso and composer" , "One on the fiddle" .)
