Soft, easily digestible pickle (6)
I believe the answer is:
plight
'pickle' is the definition.
(I've seen this before)
'soft easily digestible' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano').
'easily digestible' becomes 'light' (light and easy to digest food).
'p'+'light'='PLIGHT'
(Other definitions for plight that I've seen before include "Dangerous or difficult situation" , "Unfortunate situation" , "Pledge; predicament" , "State" , "Predicament, difficulty" .)
