What bride brings — exactly right note, we hear (9)
I believe the answer is:
trousseau
'what bride brings' is the definition.
(a bride collects a trousseau for her marriage)
'exactly right note we hear' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
'note' could be 'e' (musical note) and 'e' is found within the answer.
'we' could be 'us' and 'us' is found within the answer.
This explanation may well be incorrect...
(Other definitions for trousseau that I've seen before include "collection for union" , "Clothes, linens etc of a bride" , "Bride's accoutrements" , "Stuff for the bottom drawer" , "Clothes collected by bride-to-be" .)
