This in an update on a prior series from Oct. ’16 on four beat gaits.
A while back I wrote a bit on four beat canters & lopes. In a footnote at the bottom, I mentioned the four-beat gallop as well as a non-standard gait that is sometimes four beat: the break.
We’ll take a quick tour of our understanding of this “gait,” seen most often out of the starting gate, but first lets look at the related gallop. Prior to Muybridge’s 1870’s photographic study of equine locomotion, running horses were depicted stretch out, both hinds together behind the horse and both fore together in front of the horse, like this:
And that was that. Right? Well…not quite. In the last decade or so, we’ve revisited this idea with new film technology. We need to add a few caveats. The frames above are of a mare galloping at the Palo Alto racetrack in California in 1878. The gallop exhibited by this mare is the most common way of going for horses in that gait, with the footfalls being hind, hind-opposite fore, fore, followed by a moment of suspension with all four legs curled in towards the center of the body. It is not, however, the only footfall pattern for the gallop, and the gallop is certainly not all we see from modern racehorses. The break is likely the root of the splay legged depictions of the gallop. Earlier versions include:
This is something that was “disproven” by Muybridge, but it turns out actually happens. The gap between the hind pair and the front pair becomes much more pronounced, and the hinds occasionally push off together (though often still landing a half beat apart).
