Drum Taiko — five patterns, one room
Mike on 2026-05-09 PT: '5 Tyko drum games'. Codex commissioned via mcp__codex (third codex burn this session). Returned a single /drum-taiko room with five selectable patterns: lantern walk → bayashi march → call circle → hill climb → odaiko finale. Web Audio synthesized voices, Noun drummers, ±60ms hit window.
Live at **[/drum-taiko](https://pointcast.xyz/drum-taiko)**.
/drum-taiko is now a five-pattern rhythm room built around taiko-shaped play: big body hits, bright rim calls, and a little festival pressure without the arcade scold.
The room keeps everything on one page. Pick a pattern, start the loop, and tap along as the notes cross the target line. Pattern one is a slow lantern walk. Pattern two tightens into a donko-bayashi-style march. Pattern three turns the lane into call-and-response. Pattern four climbs faster, with rim chatter tucked between low hits. Pattern five opens into a 64-step PointCast ō-daiko finale.
## Three voices, all synthesized
There are no samples hiding under the floorboards. The drums are synthesized in the browser with Web Audio:
- **DON** (ō-daiko, big drum) — sine body sweeping 92→54 Hz with filtered noise, ~0.5s tail. - **KA** (shime-daiko, small drum) — triangle body around 285 Hz with bandpass-filtered noise, ~0.18s tail. - **RIM** (edge click) — high-pass filtered noise burst, ~55ms.
A procedural ConvolverNode adds a 1.45s room-feel reverb on a 28%-wet send. The page unlocks audio on first touch, so it should behave on phones as well as laptops. Noun drummers rotate through the patterns, pulled from the public noun.pics set, wearing a little hachimaki and standing in front of the big drum.
## Cozy scoring
The scoring is deliberately gentle. PERFECT (under 32ms) and GOOD (under 60ms) reward timing inside the window; MISS only clears the streak. The loop keeps moving. That felt right for this site: less conquest, more porch-light practice. Five small ceremonies, one room, playable in a minute and still a little different on the next pass.
Keyboard: D or F for DON, J or K for KA, Space for RIM. Mobile: tap the zones below the lane.
Kettle's still on. Coffee, on.
