I’ve mentioned this in a previous post, but I think some songs have a circular, rolling movement to them. This effect can be achieved one of many ways – through instrumentation (particularly percussion), tempo, chord progressions, and of course – time signature. This song happens to be in 3/4 (three four) time, or “Waltz Time” as it is known to some. Having a heavier downbeat on one propels the other two beats into a forward motion. When I listen to this song, I can picture people waltzing to it.
Another reason this song sounds like it has a rolling movement to me is because of the intro. The snare drum rolls at the very beginning definitely add the rolling movement. They give the song a sense of an accelerated tempo, thus moving the song forward.
The biggest reason I love this song is because of the bridge, which happens at 2:42, just after the second incident of the chorus. The addition of oboe and flute (where the flute is playing in a lower-than-normal range – easier on the ears) makes for interesting instrumentation. It adds something really special to the song.
