Soft music from duos (5)
I believe the answer is:
pairs
'duos' is the definition.
('pair' can be a synonym of 'duo')
'soft music' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano', soft).
'music' becomes 'airs' ().
'p'+'airs'='PAIRS'
'from' is the link.
(Other definitions for pairs that I've seen before include "golfing matches" , "Duos" , "Couples" .)
