'piano salesman managed to ring perhaps before lunch' is the definition.
I can't tell whether this defines the answer.

'piano salesman managed to ring' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'salesman' becomes 'rep' (sales representative).
'managed' becomes 'ran' (both can mean organised or was in charge of).
'to ring' becomes 'dial' (as in dialling a phone).
'p'+'rep'+'ran'+'dial'='PREPRANDIAL'
