'revamp a quiet duet somewhat' is the definition.
I can't tell whether this defines the answer.

'revamp a quiet duet' is the wordplay.
'revamp' is an anagram indicator (I've seen 'revamped' mean this).
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'a'+'p'+'duet'='apduet'
'apduet' anagrammed gives 'UPDATE'.

Can you help me to learn more?

(Other definitions for update that I've seen before include "Brief" , "change of status" , "Latest information" , "Latest news" , "Modernise, modify" .)

I've seen this clue in The Globe and Mail.
