'what you'd associate with beethoven' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'true master possibly around piano' is the wordplay.
'possibly' indicates an anagram.
'around' is an insertion indicator.
'piano' becomes 'p' (musical abbreviation).
'true'+'master'='truemaster'
'truemaster' anagrammed gives 'eartrumets'.
'eartrumets' placed around 'p' is 'EAR-TRUMPETS'.
