- Can it convert sheet music or staff notation to solfa?
- Yes. Snap or upload a photo or PDF of a printed, handwritten, or hymnbook score and DomiSol's image-to-score recognition returns an editable solfa (or jianpu) score. You can also import a MusicXML or MIDI file from MuseScore, Finale, Sibelius, or any DAW and DomiSol converts the staff notation to solfa or jianpu in your browser.
- Does it support SATB four-part harmony?
- Yes, convert a single melody into Soprano, Alto, Tenor, and Bass with one click, then edit each voice independently. Lyrics align under every part.
- Can the same editor write jianpu (numbered notation)?
- Yes. DomiSol writes both tonic solfa and jianpu, and flips between them on any score with one click, the music stays the same, only the glyphs change. See the dedicated jianpu editor page for details.
