Hi everyone,
We recently added another tool for the teaching of note names. It is now possible to use solfege names inside note-heads. Go to layout settings > Notes heads > Shape, and select either "Solfege (with Ti)" or "Solfege (with Si)".
You can also choose between fixed-do and movable-do: https://flat.io/updates/choice-between-movable-do-and-fixed-do
Have a wonderful day, Cyril & The Flat for Education team
