Hop on an arc

Arcs: a hop to its right and a hop back, the body rising and falling on a curve as it goes across, the arms swinging round from the shoulders and the head tipping with each hop.

What it is for

It is the Arcs in animation lesson's move. Use it for a playful hop across, a skip to one side and back.

The principle it shows: arcs

Living things move on curves. The body goes across at an even pace while it rises fast and slows at the top, then falls faster, so its path through the air is a curve. The arms swing round from the shoulders and the hands draw curves too. The first try edit breaks the arc, so you can see the difference.

Try this

Reach the far side by the top of the hop instead of halfway. The path turns into a corner, across and then straight down, and the hop stops looking natural.
In the program: ramp · to.part:root~side 12.5 → 25
Tip the head 20 degrees into the first hop instead of 8.
In the program: ramp · to.part:head~tilt -8 → -20

How it differs from Jump with anticipation

Jump with anticipation goes straight up and down on the spot; this hop travels.

Works on

The two in the film above, and what the move turns on each: worked out by the build, which plays the move on each body and checks what moves. Nobody types this table.
Who	Moves?	What moves
Sunny (one of the six people)	yes	whole body, body, head, arms, legs
Grump (an animal on four legs)	yes	whole body, turns, body, head, front legs, back legs, tail, ears
