In plain speak, FLAC is like buying an Axe-FX with all these guitar sounds that you’re never gonna use, and MP3 is like buying a Boss MT-2 Metal Zone — there’s less in there, but it doesn’t screw around with needless bells and whistles. It just takes you straight to Toneville.
One such example of horizontal hemiola that follows a similar design appears in George Frideric Handel’s iconic “Alla Hornpipe” from his Water Music Suite No. 2. In the video below, the hemiola occurs about 13 seconds in. It’s easiest to notice this happening in the harmony voices, which switch from a 3 feel to a 4 feel, with quarter notes being momentarily grouped in sets of four and groups spreading across the bar line. Without changing time signatures, the pulse of the music momentarily changes, resulting in a perfect example of horizontal hemiola.
