"Minute Waltz"

Tempo of a dance waltz can vary from 100 beats per minute for a slow country waltz, to 180 beats a minute for a Viennese waltz.

Time signature of a waltz is always 3/4. However, not all music with a 3/4 time signature is a waltz.

No. There are several of his nocturnes(Op. 9 No. 2) and etudes(Op. 10 No. 12) that objectively speaking, are more famous than the Minute Waltz. Nevertheless, I like Minute Waltz the most as its the 1st Chopin song I've ever learned.
