Joy, maybe, from Beethoven's second movement (7)
I believe the answer is:
emotion
'joy maybe' is the definition.
'beethoven's second movement' is the wordplay.
'beethoven's second' becomes 'e' (I can't explain this - if you can you should believe this answer much more).
'movement' becomes 'motion' ('motion' can be a synonym of 'movement').
'e'+'motion'='EMOTION'
'from' acts as a link.
(Other definitions for emotion that I've seen before include "sense" , "Hatred or love, say" , "Surprise, perhaps" , "Feeling - sentiment" , "Strong feeling as of love or hate" .)
