His last tune

 I've tried to get this right before, my father on his hospital bed after suffering a stroke. A moment that has stayed with me, poignant and beautiful. My wife arrived to see  him and that's where the poem comes in.

When he was beyond talking,

close to dying, you visited.

For want of words he could not form

he hummed a  tune,

unrecognizable, tuneless; 

and never was a tune more beautiful.
