This animation for Jean Sibelius’ Valse Triste is an excerpt from the movie Allegro Non Troppo (1976) by Bruno Bozzetto.
[I planned to post the animation Bozzetto created for Ravel’s Bolero (you can watch it here), but was not able embed a decent version here. Many thanks to Roland for sending me the link to the Bolero animation!]
