Continent, as I note (4)

I believe the answer is:

asia

'continent' is the definition.
(Asia is an example)

'as i note' is the wordplay.
'note' becomes 'a' (musical note).
'as'+'i'+'a'='ASIA'

(Other definitions for asia that I've seen before include "Stretch of land" , "The Orient" , "Thailand and its location" , "huge amount of ground" , "Tigers found here" .)

I've seen this clue in the Evening Standard.
