Quietly tie in position (5)
I believe the answer is:
place
'position' is the definition.
(place is a kind of position)
'quietly tie' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'tie' becomes 'lace' (lacing is a kind of tiing**).
'p'+'lace'='PLACE'
'in' is the link.
(Other definitions for place that I've seen before include "Locus" , "Endearingly pretty" , "Identify -- station" , "vacancy" , "square?" .)
