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.
I probably cheated by throwing a festival in the mix, but there are a lot of great songwriters playing Gigawatts Festival, a 3-day romp in East Williamsburg featuring 80+ bands spread out at The Wick, The Well, and Our Wicked Lady. My favorites are tight dream-pop weavers Celestial Shore and art-soul-freaks Ava Luna. These guys exemplify songwriting as a true team effort, allowing for lots of colors and variations from each player. My band is playing as well (Saturday at 2:30pm); but it’s hardly worth mentioning, as I assume you’ll all still be in bed recovering after a week of taking in all of the excellent music this town has to offer!
