Conduct a sextet: take some minutes about it (9)
I believe the answer is:
behaviour
'conduct a sextet' is the definition.
'behaviour' can be an answer for 'conduct' (I've seen this before). I am not sure about the 'a sextet' bit.
'some minutes about it' is the wordplay.
'some' indicates the central letters.
'about' indicates putting letters inside.
'it' becomes 'behavior' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The middle letter of 'minutes' is 'u'.
'u' going into 'behavior' is 'BEHAVIOUR'.
'take' is the link.
Can you help me to learn more?
(Other definitions for behaviour that I've seen before include "Bearing" , "manners" , "Personal conduct" , "Conduct - performance" , "Conduct, demeanour" .)
