There is no more heartfelt music than by Robert Schumann ( 1810-1856 ), who spent the last years of his life in an asylum due to an over the years worsening mental condition.
Here an iconic work of this very special composer:
the song "Mondnacht" ( night of the moon )
( text in English )
It was as though the sky
had silently kissed the earth,
so that it now had to dream of sky
in shimmers of flowers.
The air went through the fields,
the corn-ears leaned heavy down
the woods swished softly—
so clear with stars was the night
And my soul stretched
its wings out wide,
flew through the silent lands
as though it were flying home.
