Performance composed of seven out of eight clarinet pieces (7)

I believe the answer is:

recital

I'm a little stuck... Click here to teach me more about this clue!

'performance' is the definition.
(I know that recital is a type of performance)

I can't explain the rest of the clue.

(Other definitions for recital that I've seen before include "17 performance, for example" , "Article found in performance" , "Enumeration of facts" , "Chamber music concert" , "Concert performance" .)

I've seen this clue in the Evening Standard.
