DomiSol is purpose-built. Not a staff editor with a solfa plugin, not a viewer that lets you "type" jianpu — a true notation editor for the systems your community already speaks.
Write in solfa, hand it to a colleague who reads jianpu — they see numbers, you see syllables. Same data, two visual systems.
One model · two languages
Tone.js synth, note-by-note highlighting, no setup.

A billion musicians read solfa or jianpu. Every other editor treats them as second-class. We don't.
Church choir directors Nigeria · Ghana · Kenya · South Africa
" I've been arranging hymns in solfa on lined paper for 30 years. DomiSol does it on my phone, in WhatsApp. "
Music educators Schools · Seminaries · Universities
" My students learn movable-do solfege. Now they can compose, hear it, and submit a PDF — all in one tab. "
Jianpu instrumentalists China · Taiwan · Indonesia · Myanmar
" Erhu, dizi, gamelan — we've always read jianpu. Finally an editor that treats it as the first language. "
Diaspora composers Global
" I write SATB hymns for two churches — one reads solfa, one reads jianpu. One file, both audiences. "
Flat.io and MuseScore are great at staff notation. They're not built for solfa or jianpu — and it shows in the plugin chains and visual workarounds.
Every AI feature on this page is on the public roadmap. We ship the Next up tier first — then keep going. Free during beta, free tier after.

Both are movable-do systems where the tonic of the key is named '1' (jianpu) or 'do' (solfa). Solfa uses syllables like d r m f s l t and is dominant in African and British choral traditions. Jianpu uses numbers 1 2 3 4 5 6 7 and is the standard in China, Taiwan, Japan, and Indonesia. DomiSol lets you flip between them on any score with one click — the music stays the same, only the glyphs change.
Yes. DomiSol supports multi-part scores out of the box. Convert any single-melody score into Soprano, Alto, Tenor, and Bass parts with one click, and edit each part independently with the active-part selector.
Yes — every score plays back instantly through the Web Audio API using Tone.js. Each note highlights as it plays so you can sing or rehearse along. Tempo and key are editable on the fly.
Yes. Export any score to print-ready PDF in either solfa or jianpu mode. Perfect for handing out to choir members on Sunday morning.
DomiSol has a generous free tier covering single-melody scores, SATB editing, playback, PDF export, and unlimited share links. Pro and Team plans add AI harmonization, MIDI export, real-time collaboration, and white-label embedding for church management software.
Yes — the editor is responsive and the score viewer is optimized for sharing via WhatsApp on a low-end Android phone over 3G. Notes are touch-target friendly and the entire UI scrolls horizontally on small screens.
MuseScore and Flat.io are excellent staff-notation editors, but solfa and jianpu are second-class citizens — you need plugins, the rendering is wrong, and the workflow assumes Western staff notation. DomiSol is solfa- and jianpu-native: those are the editing modes, not export formats.
MusicXML import (auto-converted to solfa/jianpu) and MIDI export are on the roadmap for the Pro tier. Today, you compose directly in DomiSol or paste from text-based solfa shorthand.
Free during beta — every feature unlocked, no card, no limits. The editor opens in a single click.
