Duration-written movement compositionDV Samurai Language Player · Demo V1

How the DV Samurai mapping works

The player treats movement as a composition. A duration such as Q is one beat, H is two, W is four, E is one half and S is one quarter. A dotted value adds half. Changing BPM changes how fast those durations pass without rewriting the form.

• Step mode performs one complete duration block and pauses.
• Mirror swaps left and right for study while retaining the canonical form label.
• Loop repeats a selected movement or combination.
• Japanese voice speaks each Japanese cue; the stage and score also show romanization and English.
• Props change with the selected discipline: katana, wakizashi, bokutō, shinai, jō, naginata, yari, yumi, tessen, kusarigama, shuriken, nunchaku and theatrical smoke.

DV duration and technique key

Scope note: nunchaku belongs to Okinawan kobudō, while shinobi sword, shuriken and smoke are shown as a clearly labeled adjacent demonstration set—not misrepresented as standard samurai curriculum. Smoke is a harmless stage effect; no explosive construction is included.
