Here is my best explanation:

'quickly' is the definition.

'play in a clever way i' is the wordplay.
'play' becomes 'harp' (harping is a kind of playing).
'in' indicates putting letters inside.
'a clever way i' becomes 'sly' (I can't justify this - if you can you should believe this answer much more).
'harp' inserted into 'sly' is 'SHARPLY'.

'e' is the link.
