Couple beginning to talk without notes (7)
I believe the answer is:
twosome
'couple' is the definition.
(I know that couple can be written as twosome)
'beginning to talk without notes' is the wordplay.
'beginning to' says to take the initial letters.
'without' becomes 'wo' (abbreviation of 'without', normally with a slash).
'notes' becomes 'some' ('so' and 'me' are musical notes).
The first letter of 'talk' is 't'.
't'+'wo'+'some'='TWOSOME'
(Other definitions for twosome that I've seen before include "Couple" , "Item" , "game of golf" , "match" , "Pair, duo" .)
