Frost, for the audience, producing poetry (5)
I believe the answer is:
rhyme
'poetry' is the definition.
(rhyme is a type of poetry)
'frost for the audience' is the wordplay.
'frost' becomes 'rime' (rime is a type of frost).
'for the audience' shows a homophone (sound like) (how an audience might hear it).
'rime' is a homophone of 'RHYME'.
'producing' is the link.
(Other definitions for rhyme that I've seen before include "(Of words) sound the same" , "word pattern" , "Have identical terminal sounds" , "Verse, doggerel" , "Similarity of word-sounds" .)
