Crossword Genius

Whole time alto performed (5)

Ross

I believe the answer is:

total

'whole' is the definition.
(total is a kind of whole)

'time alto performed' is the wordplay.
'time' becomes 't' (abbreviation).
'performed' indicates an anagram.
'alto' with letters rearranged gives 'otal'.
't'+'otal'='TOTAL'

(Other definitions for total that I've seen before include "Entire sum" , "French oil and gas company" , "Complete, entire amount" , "Comprising the whole" , "The whole number" .)

I've seen this clue in The Mirror.
