Kaiser-Walzer

Jovan Stosic January 1, 2021

Kaiser-Walzer, Op. 437 (Emperor Waltz) is a waltz composed by Johann Strauss II in 1889. The waltz was originally titled Hand in Hand and was intended as a toast made in August of that year by Emperor of Austria Franz Joseph I on the occasion of his visit to the German Emperor Wilhelm II where it was symbolic as a ‘toast of friendship’ extended by Austria-Hungary to the German Empire.

Strauss’ publisher, Fritz Simrock, suggested the title Kaiser-Walzer since the title could allude to either monarch, and thus satisfy the vanity of both rulers. The waltz was first performed in Berlin on 21 October 1889. The original cover of the piano edition bore the illustration of the Austrian Imperial Crown.
