A piece from Bach I eventually master (7)
I believe the answer is:
achieve
'master' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'a piece from bach i eventually' is the wordplay.
'a piece' indicates the answer is hidden within the clue.
'ACHIEVE' is hidden in the letters of 'from bach i eventually'.
Can you help me to learn more?
(Other definitions for achieve that I've seen before include "Perform" , "Successfully bring off" , "Manage to get" , "Produce" , "'Accomplish, attain (7)'" .)
