Starting to develop new note with fragrance (7)
I believe the answer is:
nascent
'starting to develop' is the definition.
(I've seen this before)
'new note with fragrance' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'note' becomes 'a' (musical note).
'with' means one lot of letters go next to another.
'fragrance' becomes 'scent' (synonyms).
'n'+'a'+'scent'='NASCENT'
(Other definitions for nascent that I've seen before include "being developed" , "Being born - scan net (anag)" , "Coming into being, beginning to develop" , "Budding early" , "Beginning to show signs of potential" .)
