Pitch close to perfection, for example (7)
I believe the answer is:
pattern
'example' is the definition.
(pattern is a kind of example)
'pitch close to perfection' is the wordplay.
'pitch' becomes 'patter' (both can mean sales talk).
'close to' indicates one should take the final letters (the close/ending of).
The final letter of 'perfection' is 'n'.
'patter'+'n'='PATTERN'
'for' is the link.
(Other definitions for pattern that I've seen before include "Sewing plan" , "Blueprint, design" , "Representative sample" , "Ornamentation" , "Arrangement of repeated parts of design" .)
