Composer takes gold, beryllium and runs (5)

I believe the answer is:

auber

I'm a little stuck... Click here to teach me more about this clue!

'composer' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?

'gold beryllium and runs' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'beryllium' becomes 'Be' (chemical symbol).
'and' is a charade indicator (letters next to each other).
'runs' becomes 'r' (cricket abbreviation).
'au'+'be'+'r'='AUBER'

'takes' acts as a link.

Can you help me to learn more?

(Another definition for auber that I've seen is " Daniel ---, Fr. composer (Fra Diavolo)".)

I've seen this clue in the Sydney Morning Herald.
