Note gets yours truly renown (4)
I believe the answer is:
fame
'renown' is the definition.
(synonyms)
'note gets yours truly' is the wordplay.
'note' becomes 'fa' (musical note).
'gets' means one lot of letters go next to another.
'yours truly' becomes 'me' (the person who set this crossword).
'fa'+'me'='FAME'
(Other definitions for fame that I've seen before include "Musical - stardom" , "Repute" , "''... is the spur that the clear spirit doth raise (Lycidas, John Milton)" , "Renown, celebrity" , "Note" .)
