Meadow quiet in spring (4)
I believe the answer is:
leap
'spring' is the definition.
('leap' can be a synonym of 'spring')
'meadow quiet' is the wordplay.
'meadow' becomes 'lea' (I've seen this before).
'quiet' becomes 'p' (music symbol for 'piano').
'lea'+'p'='LEAP'
'in' acts as a link.
(Other definitions for leap that I've seen before include "Jump across" , "Abrupt change; spring" , "Basket" , "identify extra day?" , "vault" .)
