Note the right tie (6)
I believe the answer is:
tether
'tie' is the definition.
(I've seen this before)
'note the right' is the wordplay.
'note' becomes 'te' (musical note).
'right' becomes 'r' (common abbreviation).
'te'+'the'+'r'='TETHER'
(Other definitions for tether that I've seen before include "Restrictive rope fixed to one spot" , "Rope to hobble grazing animal" , "Restraining rope for animals" , "Tie animal to prevent from straying" , "Rope to hobble a horse" .)
