Harmony, agreement (7)
I believe the answer is:
rapport
This clue is a double definition.
'harmony' is the first definition.
(rapport is a kind of harmony)
'agreement' is the second definition.
(I've seen this in another clue)
(Other definitions for rapport that I've seen before include "Mutual harmony and affinity" , "Relation, connection" , "Feeling of affinity and harmony" , "Sympathetic relationship" , "Harmonious relationship between two people" .)
