I have a new waltz available in sheet music for ballet practice or choreography. At a length of just under three minutes, it might work as a pas de deux.
I called it the “Dreadful Waltz”, partially to try and maintain some humour in the proceedings. You could replace “Dreadful” with “Foreboding”, as the music seems to have that character, which is how I came up with “Dreadful”.
Here is how it sounds: Dreadful Waltz
