The document discusses the waltz dance form. It notes that the waltz has a triple meter feel with three beats per bar at a tempo of around 70 beats per minute. The waltz originated and gained popularity in Vienna in the 1790s. Harmonically, the waltz generally uses the same chord for the duration of a bar or two, with simple chord progressions and ornamentation. Waltzes also feature rubato, where the second beat is slightly early for a lively feel.
