Tar some sales talk (5)

I believe the answer is:

pitch

I believe this is a double definition.

'tar' is the first definition.
(synonyms)

'some sales talk' is the second definition.
(synonyms)

(Other definitions for pitch that I've seen before include "bowl" , "Hurl" , "Slope, of a roof say" , "Level of sound" , "Throw - wicket - sports field" .)

I've seen this clue in the Sydney Morning Herald.
