Lane colors per character: ● value 1 · ● value 2 · ● value 3. Lanes that are dense early and sparse late show a value being abandoned; the inverse shows a value being adopted. Lanes that fire together at the same beat show values that are momentarily co-present (often at climaxes). Beat counts vary by film (most are 40; A Few Good Men is 72; Last Samurai is 43).
