Figure nothing's right for a singer (5)

I believe the answer is:

tenor

'for a singer' is the definition.
(tenor is a kind of singer)

'figure nothing's right' is the wordplay.
'figure' becomes 'ten' (ten is a number or figure).
'nothing' becomes 'O' (looks like zero - 0).
'right' becomes 'r' (common abbreviation).
'ten'+'o'+'r'='TENOR'

(Other definitions for tenor that I've seen before include "General meaning of an utterance" , "Placido Domingo, say" , "General drift or meaning" , "Purport" , "thread" .)

I've seen this clue in the Evening Standard.
