'instrumental interludes' is the definition.
The definition suggests a plural noun which matches the answer.

'right? one has any number in torelli' is the wordplay.
'right?' becomes 'r' (abbreviation).
'one' becomes 'i' (Roman numeral).
'has' is a charade indicator (letters next to each other).
'any number' becomes 'n' (mathematical symbol for an unspecified number).
'in' means one lot of letters goes inside another.
'n' placed inside 'torelli' is 'tornelli'.
'r'+'i'+'tornelli'='RITORNELLI'
