'tony was one' is the definition.
I can't judge whether this definition defines the answer.

'bribe artist? no' is the wordplay.
'bribe' becomes 'sop' (sop can mean a concession or bribe).
'artist?' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'sop'+'ra'+'no'='SOPRANO'

Can you help me to learn more?

(Other definitions for soprano that I've seen before include "Norman, perhaps" , "Woman singing" , "(Singer of) the highest vocal range" , "chorus girl, perhaps" , "Highest adult female voice" .)
