A billion musicians read solfa or jianpu. Every other editor treats them as second-class. We don't.

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.

Closed beta — sign in with your Google account and we'll add you to the tester list.
Yes. DomiSol is a free online solfa editor (and jianpu editor) that runs in your browser, no install, no card. Write tonic solfa (d r m f s l t) or jianpu (1 2 3 4 5 6 7), hear it play back, arrange SATB, and share a link or export a PDF. Every feature is free during the public beta.
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.
Yes, three ways. DomiSol's Image → notation feature reads a photo or PDF of ANY score (printed staff, handwritten solfa, jianpu, a hymnbook page) and converts it into an editable DomiSol score; multi-page PDFs are supported. You can also import a MusicXML or MIDI file straight from MuseScore, Finale, Sibelius, or any DAW, DomiSol converts the staff notation to solfa or jianpu in your browser. Open the editor and look under the AI tab.
It uses a vision-language model that understands all three notation systems, staff, solfa, and jianpu, including handwritten ones. For clean printed scores it's near-perfect; handwriting and low-light phone snaps may need a few corrections, which is why the recognized score lands directly in the editor for you to tweak. During beta you get 5 recognitions per day, free.
Free during beta, every feature unlocked, no card, no limits. The editor opens in a single click.
