Walk and quietly behold daughter (4)
I believe the answer is:
plod
'walk' is the definition.
(I know that plod is a more specific form of the action the walk)
'quietly behold daughter' is the wordplay.
'quietly' becomes 'p' (musical symbol).
'behold' becomes 'lo' (archaic exclamation meaning 'look!').
'daughter' becomes 'd' (genealogical abbreviation).
'p'+'lo'+'d'='PLOD'
'and' acts as a link.
(Other definitions for plod that I've seen before include "Walk with effort" , "Walk doggedly" , "Trudge - policeman" , "Fuzzy type" , "Work doggedly" .)
