WARDRUM — Historical War-Drum & Battle BGM Generator

WARDRUM is a war-drum forge for every age. It composes original battle music note-by-note — thundering drums, war-horns, reeds, plucked strings and chant — and gives each civilization its own drums, instruments and musical modes, so a Roman march and a Mongol charge don’t just differ in tempo, they sound like different peoples going to war. Nothing is a recording; every render is generated fresh.

52 scenes across 13 civilizations:

• Rome — legion kettledrums & triumphal brass
• The Norse — frame drums, war-horns and low male chant
• Ottoman — the Mehter band: davul & kös drums, zurna reed, oud
• The Mongols — steppe drums, horns and a throat-song drone
• Egypt — goblet drums with ney flute and oud
• Hellas — the phalanx: aulos reed and frame drums
• Persia — kettledrums, santoor and ney
• Japan — taiko drums, shakuhachi-style flute and koto
• China — great drums, gong and dizi flute (pentatonic)
• The Celts — bodhrán, tin whistle and the carnyx war-horn
• Mesoamerica — huehuetl drums, conch, clay flute and rattles
• Africa — polyrhythmic drums, shakers and massed war chant
• The Crusade — brass, drums and Latin chant

12 battle forms: war march · charge · war call · war dance · drum feature · the horde · siege · victory rite · war cry · battle ritual · war hymn · aftermath (lament).

Perfect for battle themes and boss marches, army musters and training grounds, cavalry charges and sieges, pre-battle rituals and war chants, triumphant victories, and fallen-army laments. Drop the drums under a cutscene, or run a full ensemble as the fight’s main theme.

• Six sliders: Ferocity · Drums (sparse → thunderous) · Melody (drums-only → soaring) · Tempo · Chant (silent → roaring) · Space (reverb).
• Three selects: Form (auto or lock one of the 12), Meter (4/4 · 3/4 · 6/8), Ensemble (Drums only · Horns & drums · Chant & drums · Full ensemble).
• Four lengths: Short · Medium · Long · Epic. A live waveform with playhead and a ↻ New war-band reroll for endless variations of any scene.
• Seamless loops — every export carries LOOPSTART / LOOPLENGTH tags, so it loops with no gap as a BGM.
• Export OGG and WAV. OGG for the game, WAV for a DAW.
• One self-contained HTML file — no install, no account, works offline.
• 100% synthesized. No samples, ever.

How to use it

1. Download wardrum.html (or press ▶ to try it right here in your browser).
2. Open it in any modern browser — Chrome, Edge, or Firefox.
3. Pick a people and a battle cue, shape it with the sliders and selects, and hit ↻ New war-band for a fresh take. Push Drums and Ferocity for a heavier fight; raise Chant for massed voices.
4. Pick a length, name the file, and Export .ogg (and/or .wav).
5. Drop the .ogg into audio/bgm/ and select it as a map or battle BGM — the loop tags are baked in, so it loops seamlessly. (Want it under other audio? It works as a BGS in audio/bgs/ too — great for a drum bed beneath dialogue.)
6. It’s an ordinary OGG/WAV — works in any RPG Maker MZ/MV project, and in other engines (Godot, Unity, GameMaker, Ren’Py…).
