Rua Kita

Echo the origin.
Shape tomorrow.

Nine instruments from Sabah, recorded with the people who play them, on terms they set. A playable archive — and a sound machine built from it.

Our brand ethos

R.U.A.

Rua Kita is more than a project — it is a cultural-tech platform built on values that guide every decision, collaboration and experience we create.

R · Resonate

Listen deeply

We listen to the voices of our land — the elders, the rhythms, the oral traditions — and honour the ancestral sounds that shape our cultural identity.

U · Understand

Co-creation, not extraction

Every archive, tool and experience is developed with the communities we work with — not just for them.

A · Amplify

Into new spaces

We bring cultural heritage into new spaces — relevant for youth, accessible to the public, and visible on a global stage.

The archive · phase one

9 instruments,
documented and recorded

Tap a card to hear it. Cultural notes are documented with community partners; player, maker and village credits are confirmed with each community before they go on the page.

Sompoton
Mouth organ · bamboo and gourd

Produces harmonious, soothing sounds. Played at social gatherings and festivals, symbolising joy and connection.

Mesh + 2 splat captures

Reed drone
Gong
Metal percussion

A centrepiece of Sabahan culture, used in ceremonies, dances and celebrations. Each gong’s size and pitch carries a specific role in the ensemble.

Gong pulse
Tonggunggak
Bamboo percussion

Held at the closed end and struck at the open end with a mallet. Its rhythmic beats mimic the gong ensemble.

Bamboo cycle
Tonkungon
Bamboo zither

Played for personal enjoyment or in performance. Without a gong ensemble it substitutes for one — each bamboo string corresponds to an individual gong.

String line
Sundatang
Two-string lute

Sabah’s version of the lute, with a hollowed wooden body. Its soulful tunes accompany traditional dances, symbolising love and storytelling.

Bungkau
Jaw harp

Crafted from a type of palm and played with the mouth, plucked by hand for its twangy sound. Used for personal expression and storytelling.

Tongkubung
Bamboo stringed percussion

Struck with a mallet. Opening or closing a hole at the end shifts the tone, alternating high and low for its distinct “wub”.

Toburik
War trumpet · hollowed bamboo

Blown through a hole for a deep, resonant horn. Sounded before warriors left, and again on return if the hunt had succeeded.

Tongkawir
Bamboo idiophone

Shaken or struck for a bright, rhythmic clatter. Sounded to drive away bad omens when cicadas were heard before a hunt — if the buzzing continued, it was time to turn back.

Why now

The disappearing echoes of Borneo

01

The risk of losing what hasn’t been written

Many traditional sounds exist only in oral tradition. With elders passing on and few recordings available, we risk losing both the instruments and their meanings.

02

Who owns a sound that travels?

Without proper documentation, these histories risk being lost or misinterpreted. Cultural specialists and community leaders validate and piece together the narratives with us.

03

Lack of experiential access

Static recordings and academic research won’t keep these sounds alive. An interactive, digital-first approach is what keeps them relevant to new generations.

Sound prototypes

How it sounds.
What it can become.

Once an instrument is recorded, cleaned and mapped into a virtual instrument, it can be played in ways it never could before. These are creative takes on two of the nine — the tradition intact underneath.

Sompoton Dreams

The sompoton’s reed held and stretched until the sustain becomes the room — a creative take on an instrument played at gatherings to mean joy and connection.

A war trumpet turned into a beat. The same hollowed bamboo that once announced a warrior’s return, mapped across a keyboard and given a tempo.

Both pieces are arrangements of recordings held under consent that covers remix. The credit list travels with every file, and neither piece is offered as — or should be mistaken for — a traditional performance.

Phase two · working preview

The sound machine

Four layers, drawn from the archive. It arranges and transforms real recordings — it does not generate performances that could pass as traditional ones.

Every export ships with a credit manifest — source takes, players, communities, licence. You see the list before the download starts.

Measured tuning

These instruments are not in tune. That is the point.

Intervals are taken off the recordings themselves and stored in cents. Nothing here is snapped to the piano — a sompoton bent to a Western scale is a different instrument.

How it works

Each instrument’s intervals are measured off its own recordings and stored in cents against a reference pitch. The sound machine reads those numbers at playback and adds a few cents of drift per note, so a repeat never lands identically.

Per-instrument figures publish once the analysis is reviewed.

Stewardship

Consent is a field in the database, not a paragraph in a policy.

Nothing publishes without a signed record and at least one named credit. Partners review every cultural note before it goes live, and knowledge holders can withdraw their material.

Why this matters now

Museums preserve artefacts.
Rua preserves living knowledge.

We are building infrastructure that lets cultural traditions be documented, connected and shared across borders — a scalable model, not a one-off collection.

Roadmap

Three phases

Phase 01 · our focus now

Preservation

Field recordings of up to 15 indigenous instruments, story documentation for each, a digital archive co-created with community elders, and co-creation workshops for youth activation.

Phase 02 · next

Reimagination

AI tools to reinterpret archived sounds. New compositions by local and digital creators, and an experimental remix culture rooted in authenticity.

Phase 03 · planned

Immersion

On-ground installations for museums, festivals and tourism activations. Public-facing soundscapes tied to Visit Malaysia Year 2026, and a scalable model for other regions and cultures.

The archive is scoring
real work

Three commissions built on these instruments — a hotel identity, a documentary score and a tourism campaign — with local artists shaping the melodies.

Luma Hotel

Sumilau & Kopisozon

Sompoton, tongkubung, tonkungon and bungkau treated as textures inside a modern interpretation of Sabahan music — each instrument layered so its natural character still comes through.

Mongingia documentary

The first full documentary scored with these instruments — carrying the emotional weight of the mongigias, rural teachers who provided early childhood education where access was limited.

Beyond the browser

The archive leaves the screen

A poster series and two sound-pack volumes carry the archive off the screen — each release credited to the community it came from.
