Give public recital? What are you playing at? (7,5)
I believe the answer is:
concert pitch
'give public recital?' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'are you playing at?' is the wordplay.
I cannot quite understand how this works, but
'playing' could be 'on' (on can mean playing or performing) and 'on' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'what' acts as a link.
(Other definitions for concert pitch that I've seen before include "state of alertness" , "A universally-agreed standard" , "state of readiness" .)
