Classic, but abandoned

Abandoned luxury hotel now, but decades ago – the classic music room there.
The melody that was gone, only an abandoned piano left.
Along with a slightly yellowed booklet folded up
to the notes of the famous piece “Ode an die freude”
Music composed by Ludwig van Beethoven.
The text is composed by the playwright Friedrich Schiller.

Wildly surprising that the notes are still present after decades – fascinating.
