Jaw Harp Synth (KubizBeat)

Virtual jaw harp (kubyz/vargan) synthesizer for iOS. Play traditional instrument sounds with modern digital effects on your iPhone.

Sound Engine

Physics-based synthesis capturing the overtone-rich timbres of real jaw harps. Multiple tuning presets from various regional traditions:

• Bashkir kubyz — the original inspiration, warm resonant overtones
• Yakut khomus — bright, metallic character
• Vietnamese dan moi — delicate, high-pitched harmonics

Interface

• Touch controls — tap to pluck, slide for pitch bending
• Multitouch — overtone selection and resonance shaping
• Designed for expressive playing — not a toy, a real instrument

Effects

Built-in reverb, delay, and modulation. Range from traditional acoustic timbres to experimental electronic textures.

Recording & Sharing

Export as WAV or MP3. Share directly to SoundCloud, Instagram, TikTok. DAW import for music production.

Why This Exists

Intersection of personal roots (Bashkortostan), technology, and cultural preservation. The kubyz is a traditional Bashkir instrument that most young people have never played. This app makes it accessible to anyone with an iPhone — no instrument needed, no teacher needed.

Stack

Swift + SwiftUI + AVAudioEngine. On-device audio synthesis, no server, no internet required. Privacy-first — no registration, no data collection.
