Here is my best explanation:

'one's played' is the definition.

'line one nailed by a fool' is the wordplay.
'line' becomes 'cord' (cord is a kind of line).
'one' becomes 'i' (Roman numeral).
'nailed by' indicates putting letters inside.
'fool' becomes 'con'.
'cord'+'i'='cordi'
'a'+'con'='acon'
'cordi' inserted within 'acon' is 'ACCORDION'.
