Glimpse

“What kind of dance are the characters doing?”

A partnered swing-style two-step — Lindy-Hop family, not a solo or folk dance. The two figures dance as a pair throughout.

1. 0.0–4.4s Classic closed hold, travelling steadily across the floor with a gentle bounce about every half-second.
2. 4.4–5.4s He raises his arm and leads an underarm turn — a swing-out. The partners exchange places.
3. 5.4–7.3s Open position, facing each other at arm’s length, bouncy side steps and they pass again.

Nothing in the clip is labeled. The model is reading posture, hold and timing — the kind of thing a person sees at a glance.
