"The Guitar" by Federico Garcia Lorca
The weeping of the guitar
<span> begins.
The goblets of dawn are
smashed.
The weeping of the guitar
begins.
Useless
to silence it.
Impossible
to silence it.
It weeps
monotonously
as water weeps
as the wind weeps
over snowfields.
Impossible
to silence it.
It weeps for distant
things.
Hot southern sands
yearning for white camellias.
Weeps arrow without target
evening without morning
and the first dead bird
on the branch.
Oh, guitar!
Heart mortally wounded
by five swords.

It would be the word "however."
This is a transition word, but also a contrasting word could be "on the contrary," but that is reverting back to the original proposition.
