Songs that people describe as sounding happy tend to be up-tempo, higher-pitched, relatively loud, in a major key, and with a strong beat. Movements that people describe as looking happy share these qualities. Joyful movements are fast, big, and vertical. Happiness bounces, leaps, and jumps. It is upward-facing and expansive. A joyful body reaches out, looks to the sky, and takes up space.
