Create songs about pure heart showing self-confidence (9)
I believe the answer is:
composure
'self-confidence' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'create songs about pure heart' is the wordplay.
'create songs' becomes 'compose' (I can't justify this - if you can you should believe this answer much more).
'about' is an insertion indicator.
'heart' indicates the central letters.
The middle letters of 'pure' are 'ur'.
'compose' going around 'ur' is 'COMPOSURE'.
'showing' is the link.
Can you help me to learn more?
(Other definitions for composure that I've seen before include "State of calmness" , "Self-possession" , "Aplomb" , "Calmness and self-control" , "Calm self-control" .)
