Suffering composer lowering his final note (5)

I believe the answer is:

grief

'suffering' is the definition.
(I've seen this before)

I can't explain the rest of the clue.

(Other definitions for grief that I've seen before include "Sharp sorrow" , "Distress" , "Suffering" , "Anguish" , "Heartbreak" .)

I've seen this clue in The Guardian.
