Line dancing done before and after maybe reading some poetry (6)

'poetry' is the definition.
(I know that Rondel is a type of poem)

'line dancing done before and after' is the wordplay.
'line' becomes 'l' (used when specifying particular lines from a poem).
'dancing' indicates an anagram.
'before' says to put letters next to each other.
'and' is a charade indicator (letters next to each other).
'after' becomes 'r' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'done' anagrammed gives 'onde'.
'l' after 'onde' is 'ondel'.
'ondel' put after 'r' is 'RONDEL'.

'maybe reading some' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
