A waltz is "dance music in triple meter, written in time signature 3/4-beat. Waltzes typically have one chord per measure, and the accompaniment style particularly associated with the waltz is to play the root of the chord on the first beat, the upper notes on the second and third beats." You don't need to know this to know what a waltz is though. You know a waltz when you hear one, and if you're unsure, just try to tap along to it. If you find yourself doing a "mm-tch-tch, mm-tch-tch" or wearing a tuxedo and dancing like this you're probably listening to a waltz.
The waltz' timing makes it unique and beautiful, but its association with formal dances and old-timey slimebags makes it underappreciated and rare in most popular music. But there have been a number of really great indie waltzes over the years, so get your motherfucking tux on and hold your glasses up.
