Section of quartet here dutifully tied to the spot (8)
I believe the answer is:
tethered
'tied to the spot' is the definition.
'section of quartet here dutifully' is the wordplay.
'section of' says the answer is hidden in the clue.
'TETHERED' is hidden within 'quartet here dutifully'.
(Other definitions for tethered that I've seen before include "Restrained with a rope" , "limited movement" , "Of animal, with rope fastened to prevent straying" , "Fastened with rope or chain, like animal" , "on a leash" .)
